This study presents the different control techniques of Z-Source inverter (ZSI) and compares them for same modulation index. Different from traditional inverters, in ZSI circuit configurations simple boost, maximum constant boost can be utilized to perform DC-AC voltage conversion with shoot-through states. The operation principles are explained detail. duty ratio, factor, gain each technique c...

This paper explores Switched Inductor (SL) Zsource inverter which adjusts the voltage and have application in Fuel cells (FCs) which have achieved global attention as an alternative power source for hybrid electric vehicles (HEVs). The proposed inverter uses inductor and capacitor circuit to join the source and load circuit. On comparing with the initial Z-source inverter, the explored circuit ...

The Z-source inverter is one of the most interesting power electronic converters. Over past decades, research and development have been in high demand to meet challenges for improving converter performance with reduced weight cost while having efficiency along gain or boost factor. Since inception, tons resolutions, customizations, improvements appeared achieve these goals. To overcome common d...

In the last decades, the increasing restrictions imposed on the exhaust emissions from internal combustion engines have given a strong impulse toward the development of electric propulsion systems for automotive applications. The goal of electric and hybrid vehicles is the reduction of global emissions and global warming which in turn leads to a decrease of fuel resources exploitation. In this ...
