ABSTRACT:
An inverter device is connected to output ends of a full-wave rectifier for full-wave recification of an AC input voltage from an AC power source, and includes an inductance component in a loop formed with a load circuit including an LC resonance series for charging a DC power-source capacitor through one of a pair of switching elements, whereby a high input power factor is maintained while reducing any distortion of input current, and a control of the switching elements which function to restrain any rush current can be simplified.
