The designing a DC-Dc converter with diode rectifier involves several engineering tradeoffs that weigh efficiency against cost and complexity. Higher efficiencies can be obtained when schottky rectifiers are replaced by synchronous rectifiers, allowing lower voltage drops. In this paper auto-reset forward DC-DC converter with self-driven synchronous rectification is proposed. Auto-reset clamp which returns energy stored in the leakage inductance of the transformer to the power supply and the synchronize rectifier in input and output sides are increased the efficiency more than 93%. Further more fast transient response is achieved by applying the inductor-switching technique, which was presented in our prior work. The design of the concept is verified by experiment of 12V input and 1.8V/12A output.
