A power factor correction circuit for use with a power supply. The power supply has an input for receiving an AC input signal, a rectifier for producing a rectified AC signal and an output stage for outputting a DC output signal for driving a load coupled to the output stage. The power factor correction circuit comprises an input port coupled to the rectifier for receiving the rectified AC signal; and an inductor coupled to the input port for storing energy in response to excitation by the rectified AC signal. The excitation of the inductor is controlled through the opening and closing of a switch by a controller. A capacitor is coupled to the inductor and charged by the energy stored in the inductor when the switch is opened to produce the DC output signal. The power factor correction circuit includes a diode for blocking the charge path between the input port and the capacitor and also allowing the controller to boost the charge level on the capacitor.
