Abstract
An adaptive pulse frequency modulation for a switching power converter is provided that varies the switching frequency across a cycle of a rectified input voltage for the switching power converter From a beginning of the cycle of the rectified input voltage, the switching frequency decreases from a maximum value to a minimum value at a mid-point of the cycle and then increases from the mid-point back to the maximum value at an end of the cycle.
