摘要

本文提出了一种扩展升压开关电容嵌入式准z源逆变器(ESC-EqZSI)拓扑结构,该拓扑结构将现有有源开关电容嵌入式qZSI (ASC-EqZSI)拓扑结构的阻抗网络中的电感替换为开关电感(SL)单元,以进一步增强升压能力。它在阻抗网络中使用较少的元件,具有较高的升压能力,并且可以减小逆变器开关的电压应力。对所提出的拓扑进行了详细的操作分析,并与其他拓扑进行了比较。仿真和实验结果验证了所提拓扑的有效性。

Switched-Capacitor Embedded Quasi-Z-Source Inverters with Advanced Boosting Capability
This paper proposes an extended-boosting switched-capacitor embedded quasi-Z source inverter (ESC-EqZSI) topology, which is established by replacing the inductor in the impedance network of the existing active switched-capacitor embedded qZSI (ASC-EqZSI) topology with the switched-inductor (SL) cell, in order to strengthen a boost capability more. It has high boost ability with few components used in the impedance network, and can reduce a voltage stress on the switches of the inverter. A detailed operational analysis of the proposed topology and a comparison with other topologies are described. Simulation and experimental results are present to confirm the effectiveness of the proposed topology.
