ABSTRACT:
A power factor control circuit for an AC to DC power converter includes an inductor receiving AC rectified power. The charging time of the inductor is controlled by a switching circuit based on a comparison between a DC bus voltage and a fixed reference voltage. The circuit operates without an AC rectified line sensing network, and without a current-sensing resistor connected to the source of the MOSFET switch.
