Patent ID: 7304866

Claim:
A method comprising: providing a first control signal to control a state of a first high side switch coupled to a first path of a full bridge circuit; providing a second control signal to control a state of a second high side switch coupled to a second path of said full bridge circuit, said full bridge circuit coupled across a primary winding of a transformer; providing a third control signal to simultaneously control a state of a first low side switch coupled to said first path of said full bridge circuit and a state of a first rectifier switch of a rectifier circuit over an entire operating cycle, said first rectifier switch coupled to one end of a secondary winding of said transformer; and providing a fourth control signal to simultaneously control a state of a second low side switch coupled to said second path of said full bridge circuit and a state of a second rectifier switch of said rectifier circuit over said entire operating cycle, said second rectifier switch coupled to an opposite end of said secondary winding of said transformer.
