ABSTRACT:
For use in a power supply having a rectifying diode, a snubber circuit for, and method of moderating a reverse recovery current that flows from the rectifying diode as the rectifying diode transitions from a conducting state to a non-conducting state. The snubber circuit includes: (1) a saturable reactor, coupled in electrical series with the rectifying diode and providing a first conductive path for a first portion of the reverse recovery current from the rectifying diode and (2) a saturable reactor resetting circuit, coupled in electrical parallel with the saturable reactor and providing a second conductive path for a second portion of the reverse recovery current from the rectifying diode, the second conductive path reducing the reverse recovery current through the saturable reactor, thereby decreasing a thermal dissipation of the saturable reactor as the rectifying diode transitions from the conducting state to the non-conducting state.
