Claims

[Scope of utility model registration request]

In a drive circuit for a transistor converter, the base of a main switching transistor whose collector (or emitter) is connected to the primary winding of an output transformer is controlled by a signal from a control circuit. A series circuit of the primary winding of the pulse transformer and a control transistor connected between power supplies, a capacitor charged via a resistor from the auxiliary power supply, and a second circuit of the pulse transformer connected between both ends of the capacitor. A drive circuit for a transistor converter, comprising a series circuit of a primary winding and a second control transistor, and a circuit for filling the capacitor via an auxiliary winding of the output transformer.
