Abstract
A power converter for converting input power to output power includes a first transformer circuit, a second transformer circuit, and balance circuitry. The first transformer circuit includes a first primary winding for receiving a first part of the input power and a first secondary winding for generating a first part of the output power. The second transformer circuit includes a second primary winding for receiving a second part of the input power and a second secondary winding for generating a second part of the output power. The balance circuitry is coupled to a first terminal of the first secondary winding and a second terminal of the second secondary winding, and operable for balancing the first and second parts of the output power by passing a signal between the first and second terminals. The first and second terminals have the same polarity.
