1141183952Ocl94 Active Clamp and Reset Technique Enhances Forward Converter Performance Achieve Zero Voltage Transitions Higher Efficiency, Higher Frequency and Reduced EMIIRFI (ZVT), Switching Bill Andreycak Introduction: The buck derived forward converter is one of the nwst popular switchnwde topologies, second only to the infanwusflyback converter. High input to output step down or up in voltage is easily achieved by using the appropriate transformer turns ratio. Galvanic isolation is frequently added between the supply and load ..grounds" for increased safety and protection or to supply power to an isolated load. F or these and other reasons, the forward converter has become a cost effective solution to many power management needs. With its continuing proliferation, new opportunities emerge ……
