IMPLEMENTATION OF Z-SOURCE RESONANT CONVERTER FOR POWER FACTOR CORRECTION AND ELECTRIC VEHICLE APPLICATIONS

Abstract

The Z-Source Converter is discussed in this study in the context of EV battery charging apparatus. The concept is illustrated using the Z-source resonant converter, which is one of the topology that could be used for charging electric vehicle batteries. The Z Source Resonant Converter (ZSRC) implements Power Factor Correction (PFC) and controls the voltage at the output side automatically that too simultaneously, thanks to the Z-Source Inverter (ZSI), without going for any control circuitry or extra semiconductor devices, as traditional PFC converters do. To put it another way, the ZSN is a single-stage PFC converter family. Furthermore, because the ZSN is not affected by Shoot-Through States, it is appropriate for high-power applications, thereby increasing system stability and adding a boost function. This project describes and analyses the ZSRC-based Battery Charging System's operational principle.
