Abstract
A circuit includes a first rectifier having a first rectifier input and a first rectifier output. The circuit also includes a bridge circuit and a second rectifier. The bridge circuit is coupled to the first rectifier output. The bridge circuit has first, second, third, and fourth terminals. The first and second terminals are coupled to the first rectifier output, and the third and fourth terminals are adapted to be coupled to a primary winding of a transformer. The second rectifier has a second rectifier input and a second rectifier output. The second rectifier input is adapted to be coupled to a secondary winding of the transformer.
