Each of the converter circuit branches may contain a powerswitchingtransistor, a diode or a winding of an isolated transformer in addition to general circuit components.
An assistant 380V AC-input and multi-output switchingpower supply is introduced which is used in thick-film driving circuits for large-power IGBT(Insulated Gate Bipolar Transistor).
