Abstract
An apparatus such as a power converter includes a transformer assembly, a first series circuit path, and a second series circuit path. The transformer assembly includes multiple windings such as a first winding and a second winding. The first series circuit path includes a first circuit component disposed in series with a first winding of the multiple windings; the second series circuit path including a second circuit component disposed in series with a second winding of the multiple windings. The first series circuit path is connected in parallel with the second series circuit path.
