Abstract
Embodiments of the present disclosure provide a control method and a control apparatus for a PFC circuit and a switching power supply system. The method includes: obtaining a sampled voltage data set, the sampled voltage data set representing a sampled voltage for sampling an output voltage of the PFC circuit at a predetermined sampling frequency within target time window of a predetermined duration; based on the sampled voltage data set, determining a sampled average value of a sampled voltage within the time window; determining a difference between the sampled average value and a reference output voltage; and based on a product of the determined difference and a signal indicative of a phase of an input voltage of the PFC circuit, generating a control signal to control ON and OFF of a switching device of the PFC circuit.
