摘要
本文提出了一种用于可再生能源系统的软开关高增益交错耦合电感式升压转换器。源端交错配置降低了输入电流纹波，增强了转换器的功率容量。在输出端，电压倍增器电路通过耦合电感器（CI）提高增益。开关的零电压接通最大限度地减少了开关损耗。有源钳位消除了主开关产生的电压尖峰。CI 的漏感减轻了二极管的反向恢复问题。拟议的转换器以合理的 CI 匝数比和占空比实现了高增益。漏电能量回收和软开关可提高转换器的效率。我们开发了 200 W 拟议转换器的原型，以验证其性能。
A Soft-Switched High-Gain Interleaved DC–DC Converter with Coupled Inductors for Renewable Energy Systems
This paper proposes a soft-switched high-gain interleaved coupled inductor-based boost converter for renewable energy systems. The interleaved configuration, at the source side, reduces the current ripple of input and enhances the converter’s power capacity. At the output side, the voltage multiplier circuit increases the gain by means of coupled inductors (CIs). Zero voltage switching turn ON of switches minimizes the switching losses. The active-clamping nullifies the voltage spikes generated at the main switches. The leakage inductance of CI mitigates the reverse recovery issue in diodes. The proposed converter builds high gain with a reasonable turns ratio of CI and duty ratio. The leakage energy recycling and soft-switching can enhance the converter’s efficiency. The prototype of the 200 W proposed converter is developed to validate the performance.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
