Abstract
The present invention pertains to a switching regulator having two inductors that discharge stored energy during the switching operation to an output capacitor, which integrates the pulses and supplies an average voltage plus ripple to a load. The two inductors are each connected to one of a pair of equivalent inductors to form a common mode filter having magnetically interacting windings that introduce negligible inductance in series with a differential mode of current flow, in which the current in the winding of one of the pair of inductors opposes the current in the winding of the other pair of inductors during exposure to a common mode signal resulting in a cancellation of ripple current flow reaching the load.
