Abstract

Resonant transformer systems and methods of use are described. One aspect may include a primary winding, a secondary winding, and at least one output winding. In further aspects, a transformer may be coupled to the secondary winding. In one aspect, the output winding is coupled to rectifying circuitry, which may be coupled to one or more capacitors.
