ABSTRACT:
A snubber circuit for use with a power seimconductor switching device of a power converting circuit. The snubber circuit includes a snubber capacitor, coupled across the switching device for charging with current bypassing the switching device when the switching device is turned off. The snubber circuit also includes a transformer having a primary winding coupled in series with the snubber capacitor to conduct the flow of current discharged by the snubber capacitor when the switching device is turned on. The snubber circuit further includes an inductor, coupled in series with a secondary winding of the transformer, for regulating the flow of discharged current from the capacitor. The snubber circuit is coupled to return the energy discharged from the snubber capacitor to a power source to which the power converting circuit is coupled.
