It is being promoted along with the development of LSI technology. There has also been a strong demand for thinner transformers. In order to meet this demand for thinner transformers, the inventor has proposed a thin transformer constructed by abutting two ferrite plates provided with convex portions. By changing the winding ratio of the primary coil and the secondary coil, various output voltages can be obtained from the secondary coil side with respect to the voltage V 0 on the primary coil side, which can also be applied to thin transformers. be done. However, there is a drawback that the output voltage in this case is limited to an integral multiple of the lowest output voltage that can be extracted.

る。 For some electronic devices, when the minimum output voltage is 10V, various output voltages such as 12.5V, 13V, 17V, 19V, and 25V are not necessarily integral multiples of the minimum output voltage, but are fractional multiples. It often happens that you want to get . When attempting to obtain such a transformer, various complications arise when using conventional methods.
