提出了一种由两个并联的基本Boost变换单元和一个辅助电感组成的新型软开关交错式Boost变流器。该转换器能够在零电压下同时导通两个有源功率开关，从而降低了开关损耗，显著提高了转换效率。由于两个并联的基本升压单元是相同的，因此对变流模块的运行分析和设计变得非常简单。搭建了实验室测试电路，电路运行结果与理论分析吻合较好。实验结果表明，该转换模块性能良好，输出效率高达95%。
This paper proposes a novel soft-switching interleaved boost converter composed of two shunted elementary boost conversion units and an auxiliary inductor. This converter is able to turn on both the active power switches at zero voltage to reduce their switching losses and evidently raise the conversion efficiency. Since the two parallel-operated elementary boost units are identical, operation analysis and design for the converter module becomes quite simple. A laboratory test circuit is built, and the circuit operation shows satisfactory agreement with the theoretical analysis. The experimental results show that this converter module performs very well with the output efficiency as high as 95%.
