碩士 === 崑山科技大學 === 電機工程研究所 === 101 === In recent years, with the power semiconductor devices, control components such as IC and computer technology, power electronics technology and applications more widely, not only has become the electricity industry, manufacturing, automation needs, more gradually in-depth general daily lives, so power electronics has become the focus of the development of the power sector at home and abroad. It’s purpose is to power electronics to control from a source to a load between a power converter and the control forms can have a variety of types, in which all of the conversion from the source to the load and to control the type of process, the conversion efficiency is very important , assuming a great power, but it is not good enough efficiency to convert, then the circuit will generate a lot of wear and tear, and therefore how to reduce losses and improve the conversion efficiency of the circuit is very important. Because Class E resonant inverter is DC to AC of the circuit, while the direction of this study is to DC to DC to the circuit, so this paper, Class E resonant inverter do some changes in the output of adding a group doubler rectifier, resulting in a new DC to DC converter, because E category is frequency, high efficiency converter with zero voltage switching (ZVS) or zero-current switching (ZCS) can be switched with flexible features, after the actual circuit is fabricated with a set of simulation parameters can reach a maximum conversion efficiency of 92.7%, the output power of 26W, the switching frequency 72KHz new DC to DC converters.
