摘　　要：将Trans-Z源网络和五桥臂双级矩阵变换器(TSMC)拓扑结合衍生出基于Trans-Z源五桥臂TSMC全新拓扑结构。该拓扑结构不仅具有五桥臂双输出TSMC的优点,而且在拓扑结构中加入Trans-Z源网络结构使得系统克服了传统五桥臂双输出TSMC电压传输比低的不足。系统中加入Trans-Z源网络结构与常规Z源网络结构比较,系统只需一个电容,且电容电压应力更低,而且Trans-Z源网络电压传输比不仅可以通过占空比调节,也可通过变压器匝数比调节,具有更高的电压调节范围。在此搭建了Trans-Z源双输出TSMC系统,通过实验验证该拓扑结构的正确性,实验结果验证了该调制策略的可行性。A topology and modulation strategy of a Trans-Z-source five-leg dual-output two stage matrix converter(TSMC)is proposed.The topological structure not only has the advantages of five-leg dual-output TSMC,but also can overcome the deficiency of low voltage transmission ratio of the system itself when introduced the Trans-Z-source.Compared with existing dual-output TSMC,Trans-Z-source five-leg dual-output TSMC has lower Z-source capacitor voltage stress and lesser number of capacitor required,it can change the transformer turns ratio to adjust the output voltage range,with a higher voltage transfer ratio.An experimental prototype with TMS320F28335 and EPM574t144 as controller is estab-lished.The experimental results verify the correctness and feasibility of the proposed topology and control strategy.
