Abstract
The power converter includes a transformer that is coupled or decoupled from a power source by a switch controlled by a switch controller. The transformer includes a first primary winding coupled to a secondary winding. The energy stored in the leakage inductance of the first primary winding is received by a second primary winding. The energy received by the second primary winding is provided to the switch controller to power the switch controller. The second primary winding is wound adjacent to the first primary winding to receive more energy from the first primary winding.
