Wireless power transmission device, totem pole PFC circuit control method thereof and household appliance

The invention discloses a wireless power transmission device, a totem-pole PFC circuit control method thereof and a household appliance, and is applied to the technical field of power transmission, the wireless power transmission device comprises a totem-pole PFC circuit configured to be connected to an alternating current power supply, and the method comprises the following steps: after an alternating current input voltage provided for the totem-pole PFC circuit crosses a zero point, starting the totem-pole PFC circuit; the duty ratio of the first pulse signal is gradually increased based on the initial duty ratio, so that the conduction time of a high-frequency main conduit in the totem-pole PFC circuit is increased step by step, and the first pulse signal is used for driving the high-frequency main conduit; after the duty ratio of the first pulse signal is increased to the target duty ratio, if the current in the totem-pole PFC circuit is larger than the reference current value, a high-frequency synchronou
