Abstract
The present invention discloses a single-stage power factor correction circuit that includes a first rectifier, a second rectifier, a full bridge rectifier, a capacitor, a seventh rectifier, a fly back transformer, and a switch. Unlike traditional single-stage power factor correction circuits, the present invention just needs to pass through two rectifiers at positive and negative half cycles, so as to reduce the conduction loss and lower the temperature of the power supply.
