Known voltage converter (RF patent No. 2343615 "Reversible voltage converter for transferring electricity between AC and DC networks", IPC 2006.1 H02J 9/06, patent holder: Closed Joint Stock Company "IRIS" (RU)), consisting of alternating voltage AC networks connected in series current with a group of consumers of AC voltage, the first current sensor, the first filter, the first inverter-rectifier, the second filter, the second inverter-rectifier, transformer, the third inverter-rectifier, tr This filter, DC voltage network with battery; a second current sensor, a first and second voltage sensor, an analog-to-digital converter, first, second and third blocks of power key drivers, a microcontroller with random access memory, a discrete input-output module, an indication and control panel, a real-time clock, non-volatile memory device, information bus adapter, information bus, external control system; the information output of the first current sensor is connected to the first input of the analog-to-digital converter, the input-output of the AC voltage network with a group of AC voltage consumers is connected to the second input through the first voltage sensor, the output of the analog-to-digital converter is connected to the first input of the microcontroller with random access memory , a real-time clock is connected to the second input of the microcontroller with random access memory, and a non-volatile memory is connected to the third input device, the display and control panel is connected to the first input-output of the microcontroller with random access memory via a discrete input-output module, an external control system is connected to the second input-output through the information bus adapter and data exchange bus, the first output of the microcontroller with random access memory through the first block of drivers of power switches connected to the control input of the first inverter-rectifier of the first and second groups of consumers of DC voltage, and the protection and uninterruptible power supply with a battery, the first group of DC voltage consumers is connected to the output of the second filter, the second group of DC voltage consumers is connected to the output of the DC voltage network with the battery, the protection unit is connected to the gap between the third inverter-rectifier and the third filter, the second current sensor is connected to the gap between the third filter and the DC voltage network with the battery, to the third analog-to-digital input of the second converter, the information output of the second current sensor is connected, the input / output of the DC voltage network with the battery is connected to the fourth input through the second voltage sensor, the second output of the microcontroller with random access memory is connected to the control input of the second inverter-rectifier through the second block of power key drivers, the third output through the third block of drivers of the power switches is connected to the control input of the third inverter-rectifier, the output of the AC voltage network a ka with a group of consumers of AC voltage is connected to the input of an uninterruptible power supply with a battery, the output of an uninterruptible power supply with a battery is connected to the corresponding power inputs of a microcontroller with random access memory of an analog-to-digital converter, the first, second, and third block of power key drivers, module discrete input-output, display and control panels and information bus adapter.

The main disadvantages of this voltage converter (analog):

- the use of triple conversion (using the first, second and third inverter-rectifier) of the AC voltage into a DC voltage and vice versa;

- due to the fact that only one AC network is used for the converter’s power supply, uninterrupted power supply to consumers (group of AC voltage consumers, first and second group of DC consumers) after voltage loss in this network is provided by using the energy stored in the battery (incoming into the network of DC voltage). This determines the use of a battery of sufficiently large capacity (appropriate dimensions and cost), requiring regular technical maintenance;

- as part of an uninterruptible power supply for low-current components of the converter (microcontroller with random access memory, the first, second and third block of power key drivers, etc.) there is also another rechargeable battery.

The closest in execution analogue, adopted as a prototype of the invention, is a multi-channel uninterruptible power supply device (RF patent No. 2221320 “Uninterruptible power supply device multi-channel stabilizing”, IPC 8 H02J 7/34, name of the patent holder: Nikitin I.E., Bushuev V. M.). A multichannel stabilizing uninterruptible power supply device containing a network rectifier connected to an industrial AC power supply with AC terminals and DC to the input terminals of the charge-buffer converter (ACB) with DC terminals, the DC output of which is connected to the terminals of the backup battery and to input terminals of DC voltage converters (PN) by the number of channels of the output voltage, while the CBP and PN converters are made according to high frequency energy conversion circuit and consist of a first inverter, a control unit with a PWM controller and a transformer-rectifier unit (TVU), the primary winding of the transformer of which is connected to the AC terminals of the first inverter, the control terminals of the first inverters ZBP and PN converters are connected to the output the outputs of the corresponding control node, and the DC outputs of the TVU form the output terminals of the corresponding CBP and PN converters, and a second invert is introduced into each PN converter p and a control pulse commutator (KIU), and the TVU output transformer of each PN converter is equipped with a second primary winding, which is connected to the AC terminals of the second inverter corresponding to the PN converter, the input terminals of the second inverter are connected to the DC terminals of the network rectifier, and the output terminals the control node of each converter PN connected to the input terminals of the corresponding KIU, the first output terminals of which are connected to the control terminals of the first invert ora, and the second output terminals to the control terminals of the second inverter, and the voltage control terminal to the DC terminals of the network rectifier.

The disadvantages of a multi-channel uninterruptible power supply device according to the prototype is the following:

- the device provides the possibility of uninterrupted power supply for only two consumers with direct current voltage and uninterrupted power supply of consumers with alternating current voltage is not provided;

- due to the fact that only one AC network is used to power the device, the uninterrupted power supply to consumers (connected to the DC outputs of the TVU) after voltage loss in this network is ensured by using the energy stored in the battery. For a sufficiently long uninterrupted operation of responsible consumers (as in the case with the analogue), the use of a battery of sufficiently large capacity is also required.

In addition, the composition of the power equipment of this device is redundant, since two inverters are used as part of the output voltage converters to power consumers, one of which works only from the storage battery, and the second only from the industrial power supply network (through the network rectifier). This device uses "control nodes with a PWM controller", which in modern power electronics, as a rule, are implemented on the basis of universal integrated circuits - microcontrollers. Therefore, in the description of the invention we will use the term: "microcontroller" instead of "control unit with a PWM controller", as in the prototype.

The aim of the invention is to ensure the continuity of the guaranteed power supply to consumers with DC and AC voltage, associated with the solution of the following complex of tasks:

- the ability to use for power multi-channel uninterruptible power supply simultaneously two networks (main and backup) alternating current;

- ensuring the possibility of dividing uninterrupted power supply of consumers in a multi-channel unit into two main groups: a group of non-responsible consumers allowing a short interruption of power supply, and a group of responsible consumers requiring a complete uninterrupted power supply;

- providing effective normal, accelerated and other battery charges;

- reduction of the nominal capacity of the battery (respectively, dimensions and cost) to a value sufficient only to ensure switching processes from the main to the backup AC network and vice versa, as well as to continue the work of only responsible consumers for a short (several minutes) time period required for trouble-free completion of their work (for example, the correct completion of the system software of computer equipment) after turning off the main and ervnoy AC;

- when disconnecting the main or backup AC network, providing a short interruption in the power supply of several groups of non-responsible consumers with an alternating sinusoidal single-phase current voltage of ~ 50 Hz, 230 V;

- uninterrupted guaranteed power supply of a group of responsible consumers with an alternating stabilized sinusoidal single-phase current voltage of ~ 50 Hz, 230 V;

- when disconnecting the main or backup AC network, ensuring a short interruption in the power supply of a group of non-responsible consumers with a highly stable DC voltage = 28.5 V;

- uninterrupted guaranteed power supply of responsible consumers with a highly stable DC voltage = 28.5 V;

- increase the fault tolerance of the unit due to the parallel operation of several modules of the same type converting to a single load and, as a result of this, increasing the reliability (uninterrupted) power supply for responsible consumers.

The proposed uninterruptible power supply unit operates as follows.

Before starting work, it is necessary to supply power to the uninterruptible power supply unit from the main 2 or standby 25 network of AC voltage 3 ~ 50 Hz, 230 V. When you turn on one of the networks (main 2 or standby 25 network) or both networks immediately get the first power supply 9 and / or a second 18 power supply. Through the block of decoupling diodes 14, the supply voltage from one of the operating power supplies (9 or 18) is supplied to the power input of the first microcontroller 15. Since the design of the uninterruptible power supply unit provides that the rated output voltage of the first power supply 9 is slightly (a fraction of volts) greater than the rated output voltage of the second power supply 18 during their simultaneous operation, the block of decoupling diodes 14 passes current that feeds the first microcontroller 15 only from the first power supply 9, at the same time "isolating second power supply 18, the microcontroller 15 from the first (i.e., second power supply 18 in this case runs unloaded and stored in a "hot standby"). In the event of the disappearance of voltage in the main network 2 and the presence of it in the backup network 25, the current supplying the first microcontroller 15 will begin to come from the second power supply 18. The first microcontroller 15 determines the value of the voltage of the main network 2 in accordance with the program “stitched” in its memory and, if it is in an acceptable range of values (for example, ± 10% of the nominal value), using the first output, it gives a response signal to the control input of the first switch 4. In this case, the main network 2 is connected to a radio interference filter 3, which performs high-frequency voltage filtering, which then passes through the first transformer 12 to the first 8, second 13, and third 17 groups of consumers of AC voltage 1 ~ 50 Hz, 230 V. Simultaneously from the first output of the first transformer 12 receives power from the fan control circuit 6, which, using the first air temperature sensor 7 (installed in the upper part of the internal volume of the uninterruptible power supply unit), depending on the current temperature during spirit turns on / off the fan unit 5, which provides forced cooling unit. In addition, the AC voltage filtered from high-frequency interference in the main supply network 2 passes through the first rectifier 21, the pulse-switching overvoltage filter 22, the power transistor IGVT switch 23, and the third radio noise filter 24, converting to DC voltage. Monitoring the DC voltage at the output of the third radio interference filter 24, the microcontroller 15, using the third voltage sensor 16, performs PWM control of the power transistor IGBT key 23 using the driver block of the power switches 20 through the input of the logical AND circuit 28. When the output voltage value the third radio noise filter 24 below a predetermined comparator 29 gives the second input of the logic circuit “I” 28 an enable signal “I”, which passes the PWM control signals to the power transistor IGVT key 23 from the microcontroller 15. When the voltage value at the output of the third filter of the radio noise 24 is increased above the value set for the first input of the comparator 29, a voltage is supplied that is greater than the voltage supplied to its second input from the block of isolation diodes 14, as a result of which the comparator 29 outputs a logical “And” to the second input of the circuit 28 inhibit signal "0", which instantly blocks the passage of the PWM control signals to the power transistor IGVT key 23. After that, the voltage at the output of the third filter, the radio noise 24 is reduced and the comparator 29 again provides the second input of the logical AND circuit 28 is the enable signal “1”.

In the uninterruptible power supply unit, the output of the third radio interference filter 24 forms the so-called “Common DC voltage bus", the voltage from which is supplied to the third 46 and fourth 59 power supply units, which ensure the operation of the second 49 and third 62 microcontrollers, respectively, to the input of the first 40 and second 53 inverter, as well as to the power supply unit 59 and to the input of the inverter 53 of the first module for converting direct voltage to direct voltage 70, to similar elements of the second 79, third 80 and fourth 81 of the constant conversion module voltage to a constant voltage, to the power supply 87 and to the input of the inverter 82 of the first module converting DC to AC voltage 85, to similar elements of the second module converting DC to AC voltage 94.

In addition, the voltage of the "Common DC voltage bus" is supplied to the decoupling diode 45 (in this case, to the cathode of the decoupling diode 45). Further, the first microcontroller 15, with the help of the fourth output in accordance with the program “stitched” in its memory, outputs to the fourth input of the second 49 and third 62 microcontrollers, as well as to the fourth input of the microcontroller 75 of the first module for converting direct voltage to direct voltage 70 and to a similar microcontroller second 79, third 80 and fourth 81 of the DC-to-DC voltage conversion module, to the fourth input of the microcontroller 90 of the first DC-to-AC conversion module yazhenie 85 and a similar second microcontroller DC converting unit 94 into an AC voltage command "Get Started". When setting up the equipment controlled by the first microcontroller 15, for automated monitoring of the state of power supply networks (2 and 25), the operability of the channel for converting AC voltage to DC (rectifier 21 - filter of pulse-switching overvoltage 22 - power transistor IGBT-key 23 - third radio interference filter 24 ), adjusting the parameters of the voltage conversion process, the first control panel and display 11 are used.

Having received the command “Start work”, the second microcontroller 49 using the fourth voltage sensor 47 determines the value of the DC voltage at the input of the first inverter 40 and generates control actions on it through the second block of drivers of the power switches 48. The voltage generated by the first inverter 40, after filtering the first filter 41 enters the battery 43, providing its charge. For optimal control of the two-stage charge process (1st stage: at constant current equal to 10-hour charge current, 2nd stage: at constant voltage with a decrease in charging current from approximately equal to 10-hour current to almost zero) of the battery 43 , the second microcontroller 49 using the first current sensor 42, the fifth voltage sensor 50 and the second air temperature sensor 52 (installed in the battery compartment 43) receives respectively the current values of the charging current, voltage at the terminals and the ambient temperature of the battery 43. After charging the battery 43 to the minimum required capacity (to ensure uninterrupted power supply for the responsible consumers of groups 71 and 86 after disconnecting the power supply networks 2 and 25), the second microcontroller 49 outputs the second output to the control input of the third switch 44 is a trip signal. In this case, the battery 43 is connected to the decoupling diode 45 (in this case, to the anode of the decoupling diode 45). Since the design of the uninterruptible power supply unit provides that the value of the DC voltage coming from the output of the third filter of the radio noise 24 to the cathode of the decoupling diode 45, always slightly exceeds the value of the DC voltage coming from the battery 43 to the anode of the decoupling diode 45, decoupling diode 45 " isolates "the battery 43 from the" Common DC voltage bus "of the uninterruptible power supply unit. When setting up equipment controlled by the second microcontroller 49, for the automated control of the state of the battery 43, and the adjustment of its charge parameters, a second control and indication panel 51 is used.

In turn, having received the “Get Started” command from the first microcontroller 15, the third microcontroller 62 using the sixth voltage sensor 60 determines the value of the DC voltage at the input of the second inverter 53 and generates control actions on it through the third block of power switch drivers 61. AC voltage the current generated by the second inverter 53 is lowered by the second transformer 54 (also providing galvanic isolation of the conversion channel), converted by the second rectifier 55 and the second filter 56 into a DC voltage and supplied to a group of consumers of a stabilized DC voltage = 28.5 V 58. For optimal regulation of the process of converting the DC voltage supplied to the input of the second inverter 53 into a DC voltage = 28.5 V for a group of consumers 58, the third microcontroller 62 using the seventh voltage sensor 63 and the second current sensor 57 receives, respectively, the current values of the output voltage and the output current of the conversion channel. When setting up equipment controlled by the third microcontroller 62, for the automated monitoring of the operability of the DC-to-DC conversion channel (second inverter 53 - second transformer 54 - second rectifier 55 - second filter 56), adjusting the parameters of the voltage conversion process, a third control and indication panel 64 is used.

Similarly to the third microcontroller 62, the microcontroller 75 of the first module for converting direct voltage to direct voltage 70 operates, as well as the microcontroller of the second 79, third 80 and fourth 81 module for converting direct voltage to direct voltage, providing power to a group of consumers of stabilized uninterrupted uninterrupted voltage of direct current = 28.5 V 71. When setting up equipment controlled by microcontroller 75, for automated performance monitoring and process adjustment, The control and indication panel 77 is used to form the first module for converting direct voltage to direct voltage 70. For a coordinated, for example, uniform distribution of the load current consumed by a group of consumers of stabilized uninterrupted DC voltage = 28.5 V 71 between the first 70, second 79, third 80 and the fourth 81 modules for converting direct voltage to direct voltage, the microcontrollers of these modules exchange information on the first bus of the information exchange by 78. In addition, the presence of information exchange between microcontrollers allows, in the event of a failure in the power circuits (inverter-transformer-rectifier-filter), of one or even several modules for converting DC voltage to DC voltage (70, 79, 80 and 81), remaining efficient modules "pick up" the load current, making up for the loss of current from the failed module. If necessary, instead of supplying power to one concentrated group of consumers, stabilized uninterrupted DC voltage = 28.5 V 71, from the first 70, second 79, third 80 and fourth 81 modules for converting DC voltage to DC voltage, it is possible to supply power to several divided consumer groups (from 2 up to 4).

The microcontroller 90 of the first DC to AC voltage conversion module 85, using the first voltage sensor 88, determines the value of the DC voltage at the input of the inverter 82 and generates control actions on it through the driver block of the power switches 89. The AC voltage generated by the inverter 82 is supplied through the filter 83 to a group of consumers of stabilized AC voltage 1 ~ 50 Hz, 230 V 86. For optimal regulation of the process of converting DC voltage, input The microcontroller 90, which is fed to the input of the inverter 82, into an AC voltage of 1-50 Hz, 230 V, receives the current values of the output voltage and the output current of the conversion channel, respectively, using the second voltage sensor 91 and the current sensor 84. When setting up equipment controlled by microcontroller 90, to control the operability of the DC-to-AC conversion channel (inverter 82 - filter 83), adjust the parameters of the voltage conversion process, the control and display panel 92 is used. For a coordinated, for example, uniform distribution of the load current consumed by the group consumers of stabilized AC voltage 1 ~ 50 Hz, 230 V 86 between the first 95 and second 94 DC-to-DC conversion modules TERM voltage microcontrollers these modules exchange information on the second information exchange bus 93.

If the voltage of the main network 2 drops below the permissible level (for example, less than 0.8 of the nominal value or when the voltage disappears completely), the first microcontroller 15, in accordance with the program “flashed” in its memory, will disconnect the first switch 4 using the first output, without power the first 8, second 13 and third 17 groups of consumers of alternating current voltage 1 ~ 50 Hz, 230 V. Then, the first microcontroller 15 using the fourth output to the fourth input of the third microcontroller 62 will issue the command “Stop work”, and on the fourth the input of the microcontroller 62 of the first module for converting direct voltage to direct voltage 70, to the fourth input of the microcontroller of the second 79, third 80, fourth 81 module for converting direct voltage to direct voltage and, in addition, also to the fourth input of the microcontroller 90 of the first module for converting direct to alternating voltage 95 and the fourth input of the microcontroller of the second module converting direct into alternating voltage 94 - the command "Continue to work from the battery."

After that, the conversion channel for a group of consumers of stabilized voltage = 28.5 V 58, controlled by the third microcontroller 62, will stop working. At the same time, “for a moment” the voltage on the “Common DC voltage bus” disappears. In this case, the decoupling (high-speed) diode 45 will "pass" the DC voltage from the battery 43 to the "Common DC voltage bus", and the microcontrollers of the first 70, second 79, third 80, fourth 81 DC-to-DC converters and microcontrollers the first 85 and second 94 dc-to-ac conversion modules will continue to continuously control the conversion channels for a group of consumers of stabilized uninterrupted uninterrupted voltage current = 28.5 V 71 and for a group of consumers of stable uninterrupted AC voltage 1 ~ 50 Hz, 230 V 86. Thus, the uninterrupted power supply of two groups of consumers 71 and 86, and completely independent of the state of the main 2 and backup 25 network, it will not be disturbed for a quite definite time (for example, 10 ... 20 minutes - depending on the stored capacity of the battery 43 and the current intensity of consumption of load currents by consumer groups 71 and 86).

In the event that, after loss of power to the main network 2, the voltage value in the backup network 25 remains in the acceptable range of values, the first microcontroller 15, in accordance with the program “stitched” in its memory, will use a second output to output a control signal to the control input of the second switch 27. In this case, the backup network 25 will be connected to the first transformer 12, and the first 8, second 13 and third 17 groups of consumers of alternating current voltage 1-50 Hz 230 V again (after a short break, the specific value of which is determined mainly by the speed of the first 4 and second 27 switches ) will receive power. Further, using the channel for converting DC voltage to DC voltage (the first rectifier 21 is a pulse-switching surge filter 22 is a power transistor IGVT switch 23 is a third radio noise filter 24), the initial voltage value will be restored to the “Common DC voltage bus” direct current, which with the help of decoupling diode 45 again "isolates" the battery 43. After that, the first microcontroller 15 using the fourth output, in accordance with the "stitched" in his memory If it is a program, it will repeatedly issue the “Get Started” command to the fourth inputs of the microcontrollers of the conversion modules. As a result of this, the continuous operation of the conversion channels will continue, provided by the first 70, second 79, third 80 and fourth DC to DC voltage conversion modules 81, the first 85 and second 94 DC to AC voltage conversion modules and again (after a short break) the channel will restore conversion provided by the third microcontroller 62.

In exactly the same way, the uninterruptible power supply unit works when the first microcontroller 15 selects the initially standby network 25 as the power supply instead of the main network 2.

In the event that both the main 2 and the backup 25 power networks are disconnected, the first microcontroller 15 will lose power from the power supplies 9 and 18, the conversion channels of the groups of responsible consumers 71 and 86 will continue to work until the battery capacity 43 is exhausted, and then the unit uninterruptible power supply will completely stop working. Further continuation of the uninterruptible power supply unit is possible only after voltage recovery, at least in one of the networks (2 or 25).

The proposed unit works automatically. However, for remote monitoring and control of its work provides an external system 1, which provides the following basic functions:

- the condition of the supply networks 2 and 25;

- monitoring the performance of the equipment of the unit;

- voltage control on the "Common DC voltage bus";

- monitoring the status and process of charging the battery 43;

- control of voltage and load current of a group of consumers of stabilized constant voltage DC = 28.5 V 58, of a group of consumers of stabilized uninterrupted DC voltage = 28.5 V 71 and of a group of consumers of stabilized uninterrupted AC voltage 1-50 Hz, 230 V 86;

- adjustment of the parameters of the process of charging the battery 43;

- power failure of non-responsible consumers (a group of consumers of stabilized DC voltage = 28.5 V 58).

Thus, the uninterruptible power supply unit provides:

- power supply with an alternating current voltage of 1 ~ 50 Hz, 230 V in three consumer groups 8, 13 and 17 when one of the networks is disconnected (main 2 or standby 25) with a guaranteed short-term power outage;

- power supply with a stabilized DC voltage = 28.5 V of consumer group 58 (moreover, when one of the supply networks 2 or 25 is turned off, only a short interruption of power supply is guaranteed);

- uninterrupted power supply with stabilized DC voltage = 28.5 V of the group of responsible consumers 71 (and even with the simultaneous shutdown of the main 2 and 25 backup power supply networks, the power supply is guaranteed to last for approximately 10 ... 20 minutes);

- uninterrupted power supply with a stabilized AC voltage of 1 ~ 50 Hz, 230 V of the group of responsible consumers 85 (also with a guaranteed period of power supply preservation).

The industrial applicability of the invention is determined by the fact that the proposed uninterruptible power supply unit can be manufactured in accordance with the above description and drawing on the basis of well-known components and technological equipment and used for uninterrupted power supply to various consumers with alternating and direct current voltage at various facilities.

The proposed technical solutions are practically implemented in pilot-supply and serial samples of the ABP M uninterruptible power supply unit (technical conditions for the supply of KIAR.436115.001TU2) created by IRIS CJSC and allowing, when connected to two three-phase AC networks with a frequency of 50 Hz, voltage of 380 V to provide power for a variety of consumer groups (AC voltage 1 ~ 50 Hz, 230 V and DC voltage = 28.5 V).

Based on the foregoing and the results of our patent information search, we believe that the proposed multichannel uninterruptible power supply unit of modular design meets the criteria of “Novelty”, “Inventive step” and can be protected by a patent of the Russian Federation for an invention.
