Development of a High-Gain DC-DC Converter for Hydrogen Fuel Cell Based Electric Vehicles

Electric vehicles (EVs) powered by hydrogen fuel cells utilize a high-gain DC-DC converter to boost the fuel cell's low voltage output to the higher levels required by the electric motor and battery storage systems. Ensuring a consistent and reliable power supply is crucial for optimizing the performance and range of a car during operation. This paper introduces an innovative high-gain converter designed specifically for electric vehicles powered by fuel cells. It utilizes a unique combination of a quadratic boost converter (QBC) and a hybrid voltage doubler circuit. The design prioritizes achieving outstanding efficiency and reducing switching stress, which is essential for maximizing the performance and lifespan of fuel cell-driven electric vehicles. By conducting a thorough analysis and experimentation, we aim to confirm the effectiveness of this hybrid converter for efficiently transforming fuel cell output to meet the power requirements of modern electric vehicles. The results highlight the promising prospects of this integrated approach in enhancing the sustainability and performance of electric vehicle technology.
