Embedded Based Flyback Converter withProgrammable Switching Frequency for EfficiencyOptimization

[摘要] This paper presents an approach to Embedded Based Flyback Converter with Programmable Switching Frequency for Efficiency Optimization. The fly-back converters are popularly used in digital systems for achieving voltage regulation of dc supply. Normally the switching losses and cost is high in existing system. So here we proposed to develop an embedded based fly-back converter with programmable switching frequency in order to optimize the efficiency. The valley switching technique is used by sensing the valley point of switch voltage with Zero Voltage switching technique. The zero voltage switching technique is used hereto reduce the switching losses.
