Abstract
A PFC controller for a PFC switching power supply is disclosed. The PFC controller includes a peak controller configured to receive a feedback signal that is indicative of input power provided to a downstream power converter. The peak current controller is configured to generate a first reference current signal, while a first multiplier generates a product signal by multiplying a reference sign with the first reference current signal. A second multiplier generates a second reference current based on the product signal and a voltage error signal. A current regulator generates a current regulation signal using the second reference current and a line current. A modulator is configured to regulate the output power produced by the PFC switching power supply using the current regulation signal.
