提出了一种基于SEPIC变换器的三开关单相Z源逆变器（ZSI）。该拓扑具有升降压特性，并具有双接地的特点。此外，该逆变器的电压增益高于单相准Z源和半Z源逆变器。同时，由于线性电压增益，可以使用常规的控制方法。描述了电流拓扑的操作。最后通过仿真验证了电流拓扑的性能。
This paper proposes a new three-switch single-phase Z-source inverter (ZSI) based on SEPIC converters, which can be named SEPIC-based ZSI. This topology has the characteristics of buck-boost capability and has the feature of dual grounding. In addition, the voltage gain of proposed inverter is higher than that of the single-phase quasi-Z-source and semi-Z-source inverters. At the same time, conventional control methods can be used due to the linear voltage gain. The operation of current topology is described. Finally, the performance of current topology is verified through the simulation.
