Abstract:
A power factor correction (PFC) system includes a desired OFF period module that determines a desired OFF period for a switch of a PFC circuit based on an input voltage to the PFC circuit and an output voltage of the PFC circuit. A switching control module transitions the switch from an ON state to an OFF state when a measured current through an inductor of the PFC circuit is greater than a demanded current through the inductor and maintains the switch in the OFF state for the desired OFF period after the transition from the ON state to the OFF state.
