A circuit configuration combining a synchronous rectifier (SR) circuit for a converter with an LC snubber circuit is characterized in that the converter includes a transformer, a secondary coil of which being connected at an end to a metal oxide semiconductor field effect transistor that is parallelly connected to a resistance and a capacitance that are serially connected to each other, in order to reduce oscillation and electromagnetic interference; and that a primary coil of the transformer is serially connected at two ends to two diodes, an inductance is connected between the two diodes, and a connection end of the inductance to one of the two diodes is connected to a junction of the transformer and a main switch via a capacitance to form the LC snubber circuit. In this way, the transformer of the converter may be reset to enable regeneration of energy and upgraded efficiency of the converter.
