PURPOSE:To reduce the switching loss of a high frequency inverter by connecting a diode and a capacitor to the output side of a switching transistor, reducing the superposition of a collector current and a collector voltage, and turning ON when the collector voltage is 0. CONSTITUTION:Diodes 3, 4 and capacitors 5, 6 are connected in parallel with the output sides of switching transistors 1, 2. A pause period is provided at the drive input voltages of the transistors 1, 2, and the collector voltage is inverted by the resonance of the capacitors 5, 6 and the inductance component 7 of the circuit during the pause period. The collector voltage of the transistor 1 becomes in reverse phase to the collector voltage of the transistor 1. When the diodes 3, 4 are conducted, the transistors 1, 2 are conducted.
