Abstract
This paper focus es 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.
