Abstract

This paper proposes an improved L-Z-source inverter (L-ZSI), which is derived from L-ZSI with addition of two switching devices, one diode and one capacitor. The improved LZSI gives higher boost ability at low shoot-through duty region compared to the L-ZSI and overcome the limitations of L-ZSI. Another advantage of the proposed inverter is its expandability as same as L-ZSI. To achieve higher boosting rate further at low shoot-through region, additional cells (three diodes and one inductor) can easily cascaded at the switched-inductor cell. A 100 W laboratory prototype is developed to validate the performance of the proposed inverter simulations are shown to verify the expandability of proposed inverter.

可扩展多电池改进的l - z源逆变器
本文提出了一种改进的l - z源逆变器(L-ZSI),它是在L-ZSI的基础上增加了两个开关器件、一个二极管和一个电容器。与L-ZSI相比,改进的LZSI在低穿透空区具有更高的升压能力,克服了L-ZSI的局限性。该逆变器的另一个优点是具有与L-ZSI相同的可扩展性。为了在低穿透区域进一步获得更高的升压速率,可以在开关电感单元上轻松级联额外的单元(三个二极管和一个电感)。为了验证逆变器的性能,开发了一个100w的实验室样机,并进行了仿真,验证了逆变器的可扩展性。
