The final purpose of our research is a development of a soft-switched AC[DC converter which has a simple construction, high efficiency and low cost. In this research, we have been planning to clear up the following problems :1. Development of a development of soft-switched AC/DC converters which has a simple construction, high efficiency without electric pollution, and its experiment.2. Establishment of the design method of the soft-switched AC/DC converters. First term (1997) : First, not to generate the electric pollution, we developed a novel soft-switched AC/DC converter by using only one capacitor. Next, we have obtained the basic operating principle and characteristics such as the power and distortion factor, output voltage and its ripple ratio by the experiment. urthermore, we have developed a inductor commutation soft-switched bridge type DC/DC converter This converter has the functions of smaller noise and higher efficiency.Final term (1998) : We have obtained the design method guide for the soft-switched boost type AC/DC converter by performing the analysis for that. By the guide equation we can get the power and distortion factor, output voltage and its ripple ratio. Next these results are verified by the experiments. Above work has been presented at the meeting hold by IEEJ and accepted by the journal of IEEJ (will be appeared in May). Furthermore, this work will be presented at the IEEE Power Electronics Specialist Conference of USA hold on June. We will investigate the analysis method for other type soft-switched AC/DC converter applied our method and try to the application of the inductor commutation bridge type DC/DC converter into the AC/DC converter.

本课题的最终目的是研制一种结构简单、效率高、成本低的软开关AC[DC]变换器。在本研究中，我们一直计划解决以下问题：1。研制了一种结构简单、效率高、无电污染的软开关AC/DC变换器，并进行了实验研究.软开关AC/DC变换器设计方法的建立。第一期（1997）：首先，为了不产生电污染，我们开发了一种新型的软开关AC/DC变换器，它只使用一个电容。其次，通过实验得到了该电路的基本工作原理和特性，如功率和失真度、输出电压及其涟漪比等。最后，我们研制了一种电感换流软开关桥式DC/DC变换器，该变换器具有噪声小、效率高的特点，通过对软开关升压型AC/DC变换器的分析，得到了软开关升压型AC/DC变换器的设计方法指南。由波导方程可以得到功率因数、失真度、输出电压及其涟漪比。然后通过实验验证了这些结果。上述工作已在IEEJ会议上发表，并被IEEJ杂志接受（将于5月出版）。此外，这项工作将在美国IEEE电力电子专家会议举行的六月。本文将探讨应用本文方法分析其它类型软开关AC/DC变换器的方法，并尝试将电感换流桥式DC/DC变换器应用于AC/DC变换器。
