摘要

本文研究了一种Z源级联多电平逆变器，该逆变器的设计可使输出电压中的谐波最小化。可以实现平衡的直流链路峰值电压。发电模块由光伏板组成，光伏板连接到z源级联h桥逆变器。级联多电平逆变器可以实现分布式最大功率点跟踪，提高系统效率，实现高压/高功率并网，无需变压器。本文分析了不同的PWM开关方案和ZSI模块的工作状态，并对不同PWM方案的总谐波失真进行了比较。

Performance Metric of Z Source CHB Multilevel Inverter FED IM for Selective Harmonic Elimination and THD Reduction

This paper focuses on a Z source cascaded multilevel inverter which is designed to minimize harmonics in the output voltage. A balanced dc-link peak voltage can be achieved. The power generation module is built by PV panels which are connected to Z-Source Cascade H-bridge inverter. Cascaded multilevel inverter can achieve the distributed maximum power point tracking to increase the system efficiency and achieve high voltage/high power grid tie without a transformer. This paper analyzes the different PWM switching scheme and the operating states of a ZSI module and comparison is made with different PWM and total harmonic distortion of various PWM schemes.
