ABSTRACT:
An inverter device achieving a high input power-factor while restraining higher harmonics to be low is provided by a simple circuit structure, in which a pulsating DC voltage supplied through a rectifier is provided through an inductor to a smoothing condenser and to an inverter circuit section connected to output ends of the rectifier to be in parallel therewith, a smoothed DC voltage from the smoothing condenser is supplied through the inductor to the inverter circuit section, and a high frequency voltage is provided out of the device in response to ON and OFF operation of a switching means in the inverter circuit section.
