Abstract
A resonant inverter includes an input terminal, a first switch, a second switch, a transformer, a first resonant circuit, and a second resonant circuit. To the input terminal, an input voltage is applied. The first switch and the second switch are alternately turned on and off. The transformer includes a first winding and a second winding on a primary side. The first resonant circuit includes a first capacitive element and a first coil. The second resonant circuit includes a second capacitive element and a second coil. The first switch, the first winding, and the first resonant circuit constitute a first inverter circuit. The second switch, the second winding, and the second resonant circuit constitute a second inverter circuit. The input terminal is connected between the first winding and the second winding.
