Abstract: A reverse energy recovery circuit is located on a power conversion circuit equipped with a transformer which has a primary winding side connected to a power switch driven by a control unit. The primary winding side has a first end and a second end bridged by the reverse energy recovery circuit which comprises a first capacitor, a second capacitor, an ancillary winding and a diode. The first and second capacitors are coupled in series. The second capacitor has one end connected to the first end of the primary winding side. The ancillary winding has a first end connected to the first end of the primary winding side. The diode has a cathode connected to a second end of the ancillary winding and an anode bridged the first and second capacitors so that the diode and ancillary winding form a one way path between the first and second capacitors.
