摘要/Abstract

摘要： 针对如何提高增益和变换效率，并降低耦合电感型变换器的输入电流纹波问题，提出一种基于耦合电感
低输入电流纹波高增益DC/DC 变换器。通过引入无源零波纹电路，降低输入电流纹波，从而减小输入电流应
力; 同时，通过合理设计耦合电感变比，可实现变换器的高增益特性。通过理论分析和仿真实验结果表明，
该变换器的输入电流纹波大幅降低，并且所有开关管均实现了软开关，大大降低了开关损耗。同时，该变换器
各器件电压应力均远低于输出电压，有利于采用低耐压元件以降低导通损耗，提高变换器的性能。

Abstract: In order to further improve voltage gain and conversion efficiency，and reduce the input current ripple
of the coupled inductance converter． a high gain DC /DC converter based on coupled inductance ripple with low
input current is proposed． By introducing passive zero-ripple circuit，the ripple of input current and the stress of
input current are reduced． The high gain characteristics of the converter can be realized by reasonably designing
the coupled inductance ratio． The theoretical analysis and simulation results show that the converter has the
following advantages． Soft switch is realized in all switch tubes，and the switching loss is reduced． The voltage
stress of all components is much lower than the output voltage，which is beneficial to reduce the conduction loss
and improve the performance of the converter．

Key words: coupled inductance, low input current ripple, high gain, voltage stress
