本文提出了一种新的三开关三态单相Z源逆变器（TSTS-ZSI），根据升压电路的不同，可分为升压型TSTS-ZSI和降压-升压型TSTS-ZSI。所有的拓扑都具有升降压能力和低电压应力的优点，其中一些具有双重接地的特点。此外，升压在直流侧和逆变在交流侧是完全解耦的建议的拓扑结构。在线性电压增益方面，可以使用传统的线性控制方法，这使得控制系统非常简单。分别介绍了这两种拓扑的工作原理，并对它们进行了全面的比较。最后，通过仿真和实验结果验证了所提出拓扑的理论分析和比较。
This paper proposes a new family of three-switch three-state single-phase Z-source inverters (TSTS-ZSIs) that can be classified into two groups, boost-based TSTS-ZSI and buck-boost-based TSTS-ZSI, according to the step-up circuit. All of the topologies have the merits of buck-boost capability and low voltage stress, and some of them have the feature of dual grounding. In addition, the step-up in dc side and inversion in ac side is completely decoupled in the proposed topologies. In terms of a linear voltage gain, the conventional linear control methods can be used, which makes the control system very simple. The operating principles of the two types of topologies are described, respectively, and the comprehensive comparison between them is provided. Finally, the theoretical analysis and comparison of the proposed topologies are verified by the simulation and experimental results.
