Abstract
The present disclosure includes by controlling at least either one of a switching frequency of a switching element (S) or a duty ratio indicating an ON period of the switching element, securing delay time from voltage at both ends of the switching element reaches zero voltage by resonance of the resonant circuit (L0, C0) in an OFF state of the switching element until the switching element is turned on, and turning on the switching element within the delay time.
