| Summary: | 碩士 === 國立勤益科技大學 === 電子工程系 === 102 === As the power transfer becomes more and more widely applied, the customers’ demands for the power efficiency, size and reliability becomes higher accordingly; however, the conventional forward diode rectifying converter can hardly meet the demands.
This paper adopts the active clamp structure to combine with auxiliary switches and clamper capacitance, which can effectively restrain the voltage transient and minimize the damages caused by switch changeover, as well as improve the converting efficiency. The capacity elements can operate a wider range of input voltage. In practice, the Pulse Width Modulation controller is used for the research on efficiency improvement of forward converter. From the experimental results, the methods proposed in the study have realized the improvement results.
