Research on Interleaved Boost Converter with Coupled Inductors for Fuel Cells

摘要

Interleaved boost converters are typically used as a fuel cell power conditioner due to their low input ripple current. In this paper, based on the study of topologies, a novel converter is proposed for fuel cells combined with conventional interleaved converters, coupled inductances and switching capacitances. The converter is more conducive to reducing the input ripple current and improving the converter gain combined a reverse coupling inductor with a forward coupled inductor with the features of series and parallel topologies. Experimental results show that the converter has higher energy conversion efficiency (96%) and higher voltage ratio compared with the conventional boost converter, which can effectively inhibit the low-frequency ripple current on input and output sides. Additionally, the research method is provided in this article.
