A Comparative Analysis of Power Generation Using Solar and Fuel Cell for Charging EVs

Abstract

This paper compares results between a fuel cell model and photovoltaic system model usingbuck converter and boost converter which are DC/DC converters. It has limitations, such as a lack of maximum power to meet the application's demands and a significant input current ripple. The constant voltage controller uses its maximum power point tracking (MPPT) technology to collect the maximum power from the fuel cell and solar panel. The MPPT approach improves the efficiency of the electricity provided by the fuel cell and solar panel. The converters selected are advantageous because they reduce the ripple in the current, which might damage the fuel cell stack and solar panel. The classic DC interleaved boost converter and the buck converter using MPPT are simulated using MATLAB/Simulink. Interleaved boost converter is chosen because of its reduced passive component size and reduced current ripple. The constant voltage MPPT technique has proven consistent and linear performance in developing high-efficiency fuel cell systems or with PV systems. The comparison helps in understanding the effectiveness of replacing fuel cell for solar energy in EV charging stations to obtain a steady state power supply without intermittency.
