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.

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基于电感的升压转换器。源侧的交错配置减少了输入电流纹波并增强了转换器的功率容量。在输出侧，电压倍增器电路通过耦合电感器 (CI) 增加增益。开关的零电压开关导通可最大限度地减少开关损耗。有源钳位消除了主开关处产生的电压尖峰。CI 的漏感减轻了二极管的反向恢复问题。所提出的转换器通过合理的 CI 匝数比和占空比构建高增益。泄漏能量回收和软开关可以提高转换器的效率。开发所提议的 200 W 转换器原型是为了验证性能。
