Abstract
The feedback loop of a switching power converter controller is provided with an averaging circuit that averages either an output voltage, an error signal, or a control voltage. Regardless of which feedback signal is averaged, the averaging occurs over a first cycle of a rectified input voltage to form an averaged signal that is used by the feedback loop in a subsequent cycle of the rectified input voltage.
