Design of Dual Input Single Output High Gain Step up DC -DC Converter with modified Deer Hunting Optimization based MPPT Controller

This paper proposes a high-efficiency hybrid electric vehicle (HEV) power system powered by solar photovoltaic (PV) and battery sources. A high gain Dual Input Single Output (DISO) converter is designed for HEV applications. It regulates solar PV output voltage under source and load side disturbances. To ensure that the solar panels always deliver maximum power to load, Modified Deer Hunting Optimization (MDHO) algorithm has been used to generate switching pulses to DC-DC converter under various conditions. Simulation results obtained from MATLAB/R2024a Simulink under various load and variable solar irradiance conditions assess the converters ability to maintain a constant output voltage and demonstrate its accuracy compared to conventional methods. The system achieves a peak efficiency of 94.6% highlighting its effectiveness for sustainable transportation applications.
