| description | The invention provides an AC-DC converter and a control method of the AC-DC converter, the AC-DC converter comprises a totem-pole bridgeless power factor correction circuit, a forward DC-DC conversion circuit and a digital control system, the totem-pole bridgeless power factor correction circuit is connected with the forward DC-DC conversion circuit, and the digital control system is connected with the totem-pole bridgeless power factor correction circuit. And the totem-pole bridgeless power factor correction circuit and the forward DC-DC conversion circuit are respectively controlled by a first control subsystem and a second control subsystem in the digital control system. Wherein the totem-pole bridgeless power factor correction circuit is a bridgeless power factor correction circuit, and the totem-pole bridgeless power factor correction circuit can play a role similar to synchronous rectification while performing power factor correction by controlling on and off of a switching tube in the totem-pole bridge |
