Abstract
A high power factor rectifier circuit includes a totem pole power factor correction (PFC) circuit, a sampling resistor, a power suppl a PFC controller, and a filter. The totem pole PFC circuit includes two bridge arm units connected in parallel between a first parallel connection point and a second parallel connection point. One end of the sampling resistor is connected to the first parallel connection point and a first reference ground, and the other end of the sampling resistor is separately connected to a sampling voltage input terminal of the PFC controller and a second reference ground. A grounding terminal of the PFC controller is connected to the first reference ground. A power output terminal of the power supply is connected to a power input terminal of the PFC controller using the filter.
