Abstract
A single-stage power factor correction circuit includes a first rectifier, a second rectifier, a full bridge rectifier, a capacitor, a fly back transformer, and a switch. Unlike conventional 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, lower the temperature of the power supply, and control the voltage of the control energy storage capacitor, and stabilize voltage output.
