ータ回路。 A bridge circuit that is connected to a DC power source and bridges a load with a plurality of semiconductor switching elements, and a drive circuit that is connected to this semiconductor switching element via a transformer and alternately switches the semiconductor switching elements using an output signal from an oscillation circuit. In an inverter circuit that converts DC power supplied to the bridge circuit into AC power, a primary coil of a transformer is connected to the oscillation circuit via a capacitor, and one semiconductor switching element is connected to the secondary coil of the transformer. An inverter circuit characterized in that the other semiconductor switching element is connected directly to the output of the oscillation circuit to provide a drive signal.
