Abstract
According to one aspect, embodiments herein provide a flyback converter comprising an input, an output, a rectifier, a transformer having a primary winding and a secondary winding, a switch, the switch being closed in a first mode of operation and open in a second and third mode of operation, and a regenerative snubber circuit, wherein the flyback converter is configured such that in the first mode of operation, the DC power from the rectifier charges the transformer, wherein the flyback converter is configured such that, in the second mode of operation, the snubber circuit is configured to store leakage energy from the primary winding, and wherein the flyback converter is configured such that, in the third mode of operation, the snubber circuit is configured to provide the stored energy to the primary winding. The flyback converter may also have high power factor at the input while operating from AC input.
