Photovoltaic (PV) based Electric Vehicle (EV) charging faces challenges of low voltage output, unstable supply, and limited converter performance under changing atmosphere condition. Hence, this work aims to develop a Permanent Magnet Synchronous Motor (PMSM) driven EV charging efficiency and stability using a novel converter and control approach. The major objective of this approach is to attain high efficient EV performance with improved stability and reliability. A High Gain Switched Quasi Z Source Converter (HG-SqZSC) is utilized for boosting the output voltage of PV with higher efficiency and increased voltage gain. An Improved Dolphin Pod (IDP)- optimised Proportional Integral (PI) controller is deployed to achieve a stable power output with increased convergence speed. On the other hand, during insufficient power supply or abnormal weather conditions, a three-phase grid and battery act as the supplementary power source, thereby providing continuous power supply required for PMSM motor-driven EV. Moreover, to validate the working and efficiency of the proposed PV-energized EV motor, MATLAB/Simulink is utilized which states that, the developed system ensures to attain higher efficiency (93.3%), Voltage gain (15) and reduced Total Hormonic Distortion (THD) (0.63%). Thus, it leads to less environmental pollution with constant EV charging systems even under varying circumstances.
