Abstract:
A desired OFF period module is configured to determine a desired OFF period for a plurality of switches of a PFC circuit based on an input voltage and an output voltage. A blanking timer module is configured to output a blanking signal, set the blanking signal to a first state when a countdown timer is greater than zero, and set the blanking signal to a second state when the countdown timer reaches zero. A switching control module is configured to: transition a first switch of the plurality of switches from an ON state to an OFF state in response to (i) a measured current through an inductor of the PFC circuit being greater than a demanded current through the inductor and (ii) the blanking signal being in the second state; and maintain the first switch in the OFF state for the desired OFF period after the transition.
