Performance Analysis of PV-based DC-DC Converters for EV Charging Applications

Energy conversion requires efficient converter systems, which can convert AC to DC or DC to AC.Power electronic converters play a key role in photovoltaic systems integrated with energy storage systems like batteries.They enable efficient charging and discharging, voltage regulation, and synchronization with the grid.The switching of power electronics devices plays a significant role in DC to DC-conversion.The grey wolf optimization (GWO) metaheuristic algorithm generates duty ratios, and a PWM pulse generator generates triggering pulses.This work analyzes the ZETA converter with PV as input and EV as the application.In a MATLAB environment, a 5-by-5 PV system with Buck-Boost, SEPIC converter, and Zeta converter are simulated.The minimal output ripples support the smooth and efficient charging of EV batteries, promoting the use of clean energy.
