Simulation and Designing of Fuel Cell with Boost Converter for Electrical Vehicle in MATLAB

Abstract

This research provides a conceptual framework for developing and simulating appropriate DC-DC BOOST converters for fuel cell systems. Fuel cell technologies and power electronics are crucial in the area of renewable energy. The use of high-performance fuel cell technology is acceptable given the rising expense of fossil fuels and the expanding global need for conventional energy. The need for fuel cells will rise as they take over as the primary power source for portable applications. However, the fuel cell stack's output voltage is extremely low and insufficient to power an electric car. The three-level hybrid boost DC-DC converter was proposed in this study and can step up the fuel cell output voltage with a high voltage gain. The classic neutral clamped multi-level inverter serves as the foundation for the current converter's operation. A necessity for this application and a key component of the device as a whole is a highly efficient converter. Due to the low output voltage of fuel cells, a highly efficient converter must be created for fuel cell systems. In this study, multiple DC-DC converters with fuel cells as input sources, including Boost, SEPIC, LUO, and ZETA converters, are constructed and simulated using MATLAB. All DC-DC converters are subjected to a Total Harmonic Distortion analysis, and the converter best suited for fuel cell application is chosen based on the converter's low Total Harmonic Distortion value.
