Abstract
A converter circuit includes a magnetic core, a primary winding, a secondary winding, a main rectification circuit, and an auxiliary rectification circuit. The primary winding and the secondary winding are wound around the magnetic core. The main rectification circuit and the auxiliary rectification circuit are both connected to the secondary winding and produce output voltages having different magnitudes. The auxiliary voltage powers the control and drive circuits for both the primary switches and the synchronous rectifiers used for the main rectification circuit.
