The boost factor of active-switched inductor boost qZSI (cASLB-qZSI) is relatively high. In this paper, a new extended boost inverter, namely active-switched boost qZSI (ASB-qZSI), is proposed. Accessing higher voltage gain in higher modulation index with continuous input current and fewer components in Z-source network are the advantages of proposed inverter. The proposed ASB-qZSI structure generates higher AC output voltage than that of the conventional active-switched inductor boost qZSI (cASLB-qZSI) because it has fewer elements (one inductor and three diodes are reduced) in Z-source network and less shoot-through current. The boost factors of proposed ASB-qZSI and classic capacitor-assisted qZSI (sCA-qZSI) are the same. However, the proposed topology has fewer components; two inductors and three capacitors are reduced by adding one extra switch. The shoot-through current in proposed ASB-qZSI is decreased by half in comparison with conventional sCA-qZSI. To show the correct operation of the proposed ASB-qZSI, it is simulated with simple boost pulse-width modulation method in PSCAD/EMTDC, and then the experimental results are presented.

具有少量元件的有源开关升压准 Z 源逆变器

有源开关电感升压qZSI（cASLB-qZSI）的升压因子相对较高。在本文中，提出了一种新的扩展升压逆变器，即有源开关升压 qZSI (ASB-qZSI)。在具有连续输入电流和 Z 源网络中的较少组件的情况下以更高的调制指数获得更高的电压增益是所提出的逆变器的优点。所提出的 ASB-qZSI 结构比传统的有源开关电感升压 qZSI (cASLB-qZSI) 结构产生更高的交流输出电压，因为它在 Z 源网络中具有更少的元件（减少了一个电感和三个二极管）和更少的射通过电流。提议的 ASB-qZSI 和经典电容辅助 qZSI (sCA-qZSI) 的升压因子是相同的。然而，所提出的拓扑结构具有较少的组件；通过增加一个额外的开关减少了两个电感器和三个电容器。与传统的 sCA-qZSI 相比，提议的 ASB-qZSI 中的直通电流减少了一半。为了显示所提出的 ASB-qZSI 的正确操作，在 PSCAD/EMTDC 中使用简单的升压脉宽调制方法对其进行了仿真，然后给出了实验结果。
