Abstract

Focus of this study is on a new switched-capacitor current-fed (CF) quasi-Z-source inverter (qZSI) topology, which is derived from the conventional CF qZSI. Each capacitor of the quasi-Z-source network is replaced by a switching-capacitor cell built with two capacitors and three diodes. As our steady state analysis of an idealized converter shows, the proposed CF qZSI offers an extended regulation region and increased voltage gain. Bi-directional power transfer and a wide regulation range fit the requirements set for electric vehicle applications. Operation modes were verified by numerical simulation in PSIM.
开关电容电流馈电准z源逆变器
本研究的重点是一种新的开关电容电流馈电(CF)准z源逆变器(qZSI)拓扑,它是由传统的CF qZSI衍生而来的。准z源网络的每个电容器都被一个由两个电容器和三个二极管组成的开关电容器单元所取代。正如我们对理想变换器的稳态分析所显示的那样,所提出的CF qZSI提供了一个扩展的调节区域和增加的电压增益。双向功率传输和宽调节范围适合电动汽车应用的要求。在PSIM中进行了数值模拟验证。
