Abstract: PURPOSE:To obtain a stable high frequency drive by providing two feedback windings in a main transformer, and supplying an ON gate current and an OFF gate current to MOSFETs by the positive feedback outputs. CONSTITUTION:When a capacitor C2 is reversely charged to charge the forward voltage drop of a diode D2 in a positive direction, a current through a resistor R3 is flowed to both a capacitor C2 side and a gate of a main switch element M1.
