INVERTER CIRCUIT AND WIRELESS POWER TRANSFER CIRCUIT

An inverter circuit includes an input inductor connected in series between a direct-current power supply and a switching element partially constituting the inverter circuit, a high-frequency resonant circuit that includes a high-frequency resonant capacitor and a high-frequency resonant inductor and is connected in parallel to a switching element, and a switch having one end connected to the direct-current power supply and the other end connected to the high-frequency resonant capacitor and the high-frequency resonant inductor. The input inductor is connected in parallel to the high-frequency resonant inductor and the switch.
