Abstract
A resonant inverter includes first and second switches, first and second capacitive elements, a first coil, a second coil, a third coil, and a third capacitive element. The first and second switches are alternately turned on and off. The first and second capacitive elements are connected in parallel to the first switch and the second switch, respectively. The first coil is disposed between the first switch and an input voltage terminal. The second coil is disposed between the second switch and the input voltage terminal. The third coil and a third capacitive element are connected in series to each other and connected in parallel to a series circuit of the first and second coils. The first and second capacitive elements and the first and second coils constitute a plurality of first resonant circuits. The third coil and the third capacitive element constitute a single second resonant circuit.
