ABSTRACT:
A switching regulator for achieving soft switching comprises a pilot switch in series with a diode, and a pilot inductor connected from the junction between the pilot switch and the diode to a tap on the main inductor. A bidirectional circuit operating as a buck or a boost regulator can be achieved by replacing all of the diodes with active switches and selectively activating certain of the switches.
