Snubber

An energy recovery snubber circuit for a power converter comprises a flyback transformer driven by a converter switch M1. The snubber circuit comprises two capacitors Cl, C2 which are connected such that, when the snubber circuit is connected to a primary winding L1a of the flyback transformer, the capacitors are charged in series by current flowing in a first direction in the primary winding when switch Ml is turned OFF, to recover energy stored in the leakage inductance of the transformer, and discharged in parallel to cause current flow in a second direction in the primary winding of the transformer, to thereby transfer the recovered energy to the transformer. A snubber switch M2 may be connected between the primary winding of the transformer and the capacitors such that the capacitors are discharged in parallel when switch M2 is on.
