A power converter module includes a power transformer, a first power switch, and an active snubber circuit for recovering surge energy. The power transformer has a primary winding and a secondary winding adapted to be coupled electrically to a load. The primary winding has first and second terminals connected electrically and respectively to first and second nodes. The first power switch has a first switch terminal connected electrically to the second node, and a second switch terminal connected electrically to a third node. The first and third nodes are adapted to be coupled electrically to a power source. The active snubber circuit includes a snubber diode, a snubber capacitor, a snubber transformer, and a second power switch.
