Abstract:
1. A zero-voltage switching high-frequency inverter comprising: a first switch and a second switch that are connected in series between power sources; a third switch and a fourth switch that are connected in series between the power sources; a first capacitor, an impedance element, and an inductor element that are connected in series between a connecting path connecting the first switch and the second switch and a connecting path connecting the third switch and the fourth switch; and a second capacitor connected in parallel to the impedance element and the inductor element that are connected in series, wherein when a ratio of an amplitude of a current flowing through the impedance element (lomax) relative to an amplitude of a current flowing through the first switch and the fourth switch or a current flowing through the second switch and the third switch (lsmax) is Ar (lomax/lsmax), an electrostatic capacity of the first capacitor is C
