At T 0 , the current transformer coil current I F is raised to the planned value. The current transformer coil current I F rises to the expected position at T = T 0 , but the time required for that rise (T 0 -
T 2 ) is the toroidal magnetic field coil current as shown in A.
This is about one tenth of the time required for It to rise (T 0 −T −1 ). The vertical magnetic field coil power supply composed of the thyristor-controlled rectifier 8 excites the vertical magnetic field coil 2 (Lv) at the time when the toroidal magnetic field coil current It rises to the scheduled value, that is, at T=T 0 , as shown in C.

る。 In this way, the energization pattern of the toroidal magnetic field coil current It and the poloidal magnetic field coil currents I F and Iv must excite the toroidal magnetic field coil 3 before starting the excitation of the poloidal magnetic field coil. Therefore, at T=T -1 , a voltage of V=Vt 1 is applied by the thyristor-controlled rectifier 9 between the terminals of the toroidal magnetic field coil 3 (Lt), and T=
A predetermined current value It is obtained at T 0 , and from T 0 to T 1 thyristor control is performed to a voltage V=Vt 2 sufficient to compensate for the loss due to the resistance of the toroidal magnetic field coil 3 .

The intended purpose is achieved by providing a switching device that performs power supply switching control so that the second power supply is supplied to the poloidal magnetic field coil upon completion of excitation rise. That is, when starting up the toroidal magnetic field coil current, a part of the poloidal magnetic field coil power source is temporarily used, and when the toroidal magnetic field coil current reaches a predetermined value, the toroidal magnetic field coil power source that was being used is disconnected, and the remaining toroidal magnetic field coil power source is used. By supplying enough power to the toroidal magnetic field coil to compensate for the loss due to the resistance of the toroidal magnetic field coil using a toroidal magnetic field coil power supply, an attempt is made to obtain a power supply device for a nuclear fusion device that requires a small power supply capacity. It is something.

11 is a thyristor-controlled rectifier that supplies power to the entire excitation region of the vertical magnetic field coil 2 and at the rise of excitation of the toroidal magnetic field coil 3. A vertical magnetic field coil power supply 12 is a switch for controlling power supply switching, and when the toroidal magnetic field coil 3 is excited, the toroidal magnetic field coil power supply 10 is
The switching switch 12 is switched to the toroidal magnetic field coil side 14 so that the vertical magnetic field coil power supply 11 is applied to the toroidal magnetic field coil 3 to excite the toroidal magnetic field coil 3, and when the toroidal current of the toroidal magnetic field coil 3 reaches a predetermined value, the switching switch 12

時点で垂直磁場コイル２の励磁を開始する。 First, at the time of T=T -1 in FIG. do. In this case, the rise time of the toroidal magnetic field coil 3 is determined by the amount of power of the toroidal magnetic field coil power supply 10 and the vertical magnetic field coil power supply 11. As the excitation of the toroidal magnetic field coil 3 progresses and the current It reaches a predetermined value at T=T 0 , the gate of the thyristor-controlled rectifier of the vertical magnetic field coil power supply 11 is phase-controlled and switched to a slightly opposite polarity. The current flowing through the switch 12 is brought close to zero. After confirming that the current flowing through the changeover switch 12 has become zero, the changeover switch 12 is connected to the vertical magnetic field coil side 13. During this time, the toroidal magnetic field coil power supply 10 operates at T=
At T 0 , the DC output voltage is set to V=Vt 02 by phase control, and power supply sufficient to compensate for the loss due to the resistance of the toroidal magnetic field coil 3 is started. The above switching switch 12 allows the vertical magnetic field coil power supply 1

The poloidal magnetic field coil current 11 that was being used is disconnected, and the remaining toroidal magnetic field coil power supply 10 supplies the toroidal magnetic field coil 3 with enough power to compensate for the loss due to the resistance of the toroidal magnetic field coil 3.

That is, the embodiment shown in FIG.
When the toroidal magnetic field coil current starts to rise at = T -1 and reaches the planned value at T = T 0 , the toroidal magnetic field coil power supply only compensates for the loss due to the resistance of the toroidal magnetic field coil 3. Since it is sufficient to have a capacity that can supply electric power of The above operation is performed by the changeover switch 20, and the excitation switching operation between the toroidal magnetic field coil 3 and the poloidal magnetic field coil 2 by this changeover switch 20 is as follows:
