Abstract
An inverter device for supplying a stable, high power-factor input current while restraining higher harmonics to be low is provided by a simple circuit structure in which a pulsating DC voltage supplied through a power circuit is provided to a smoothing condenser, a direct current is provided from the smoothing condenser to an inverter circuit section, and an input current path is formed from the power circuit through an impedance element to a switching element of the inverter circuit section and to part of an oscillation circuit.
