Real-time Simulations on High-Performance Z-Source PV-Grid-Tied Inverters with DC Charger for EV Applications

Abstract

Solar power is the most prevalent green energy source for household and semi-commercial
applications. Using energy storage devices, fluctuations in solar energy collecting can be reduced
(ESS). Solar electricity can also be utilized to charge electric vehicle batteries, reducing reliance on
the grid. To qualify as such converters, they must have a limited number of steps and a separation. It
is possible to eliminate multiple stages of conversion by using the Z-source inverter (ZSI) topology.
The use of passive materials allows for the incorporation of ESS. To charge the batteries of electric
vehicles using direct current, this article describes the design, building, and operation of a modified
ZSI equipped with a split primary separated battery charger. Simulated results have been used to
demonstrate the feasibility of the proposed converter's operation.
