Abstract
A resonant inverter includes: an input capacitor; an inverter; a snubber circuit; a transformer having a primary winding connected to an AC end of the inverter; a resonant coil, a resonant capacitor, and a current sensor on the secondary winding side of the transformer; and a control unit, wherein, on the basis of current detected by the current sensor, the control unit controls switching elements so as to perform zero voltage switching at the time of turning-on, at a frequency at which a load including the resonant coil and the resonant capacitor becomes capacitive, and performs power regeneration of energy stored in a snubber capacitor to a DC voltage source.
