Abstract
Abstract An effective hybrid energy system that connects with a fuel cell, solar, and battery system is described as a renewable energy (RE) source powered electric vehicle. The consequences of designing multi‐input DC‐DC converters for various sources are thoroughly studied. The fuel cell (FC) is utilized as the major source of energy, with photovoltaic (PV) livings utilized to recharge the battery, enhance efficiency, and diminish fuel consumption. By selecting a suitable coupled inductor turn ratio, the proposed structure efficiently enhances the rate of output voltage. A coupled inductor's created leakage inductance energy can be reclaimed, resulting in a reduction in the recommended converter's power losses. Variability in RE power production and load demand are both taken into account for maintaining the power balance. In addition, a power management technique is developed and implemented in a control technique. High gain, continuous input current, low voltage stress on switches, and extensive input and output operations are some of the interesting features of the proposed converter. The converter's results are also experimentally verified with the use of a programmable DC source.
