ABSTRACT:
There is provided a zero-voltage switching high-frequency inverter capable of supplying a current of a large amplitude operation to a load, while suppressing a main switch current. The zero-voltage switching high-frequency inverter according to the present invention comprises: a first switch S1and a second switch S2that are connected in series between power sources Ed; a first capacitor C1, an impedance element R, and an inductor element L that are connected in series between a connecting path connecting the first switch S1and the second switch S2and one end of the power sources Ed; and a second capacitor C2connected in parallel to the impedance element R and the inductor element L that are connected in series.
