Abstract
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.
