  "textContent": "When a secondary battery is charged, a switch is closed, and a first boost chopper circuit, a second boost chopper circuit, and a totem-pole bridgeless power factor correction circuit, which are coupled in parallel to each other, are driven to operate in an interleaving manner, and in this state, an alternating-current voltage inputted from an AC input terminal is converted into a direct current, and the direct current is outputted from a direct current output terminal. When alternating current is outputted using an AC output terminal, the switch is closed, and the totem-pole bridgeless PFC circuit is used, and in this state, a DC voltage from the secondary battery is converted into an alternating current, and the alternating current is outputted from the AC output terminal.",
