摘要 近年来,新能源发电系统往往需要接入多种诸如基于风电、光电等多种形式的发电设备,通过多种能源的互补实现供电稳定的目标。因此,相较于单输入的电力电子变换器,应用具有双向能量流动能力的多端口变换器能够提高系统的稳定性和效率。提出了一种基于三重全桥三端口有源桥(TCF-TAB)的宽软开关(ZVS)范围高增益双向多端口直流电力电子变换器,该结构具有较高的电压增益、宽ZVS范围和对称性。分析了变换器的工作原理、稳态特性和ZVS范围,最后通过实验样机对理论分析进行验证。 During recent years,in order to realize multi energy complementation,the requirements for adaptable energy management system of dealing with various renewable source are growing rapidly.Henceforth,compared to traditional single-input converter,bidirectional multiple-input converter can be approving candidates for such circumstance as the topology has the advantages of high efficiency and stability.A triple-compound-full-bridge-based triple-port active bridge(TCF-TAB)converter with wide zero voltage switch(ZVS)range and wide conversion gain is proposed for the bidirectional operations of power flow.Operation modes,steady-sates and ZVS range are analysed.Finally,an experimental prototype is constructed to verify the feasibility of the converter.
