Abstract
A resonant power conversion device includes: a main circuit provided with a semiconductor switch, a capacitor and an inductor connected in series or parallel to the semiconductor switch; and a drive circuit configured to drive the switching element. The switching element enters an off-state or an on-state depending on a control voltage input to a gate terminal, and the drive circuit includes two or more types of control voltages, as a control voltage at which the switching element enters an off-state.
