Abstract
A power source device for supplying a high frequency AC voltage to a load. An source voltage is changed by a rectifier into a into a DC voltage that is supplied to an inverter to produce the high frequency AC voltage. The high frequency AC voltage is fed back to the rectifier where a resonant circuit resonates with the high frequency AC voltage. The inverter may be self-excited through feedback of the high frequency AC voltage. In this power source device, any pausing in the AC source voltage is filled in through the feedback and resonant circuits.
