The automobile companies in the global market focused on the recent technologies towards Hydrogen (H2) and FC-VPT to improve the Tank-To-Wheel (TTW) efficiency. Cost-effective solutions for ‘Eco’ friendly, free of emission, and high-power capacity are the inherent benefits. The DC-DC power converters play a crucial influence in boosting the fuel cell stack power through voltage conversion. Therefore, ensure the demand of the motor and transmission in the vehicles. Several DC converter topologies are proposed for various vehicular applications. State-of-the-art technology, newly developed families of the unidirectional non-isolated DC-DC Multistage Power Converter (MPC) configuration for Fuel Cell – Vehicular Power Train (FC-VPT), Renewables, and Microgrids application will be discussed with the presentation. DC-DC power converters with the new modified version are viable and cost-effective solutions with reduced size and increased efficiency. The comprehensive review, comparison of different topologies, and suitability for various applications will be discussed in the presentation, correctly applied to a small vehicle’s power train to large vehicles (bus, trucks, etc.). Finally, the advantages/disadvantages will be pointed out in the presentation for the prominent features of each converter, its challenges, and application for fuel cell (FC) technology, EVs, Microgrids, and Renewables.
