<p>In recent decades, the pairing of solar PV systems and Electric Vehicles (EVs) has become more prevalent, predominantly due to two goals: lowering energy costs and reduced greenhouse emissions. Nowadays, the Multilevel Inverters (MLIs) have grown to be the ideal choice for lower and medium-powered applications, due to their superior power quality for DC to AC power conversion. In this study, a brand-new, cutting-edge MPPT regulating technique called Golden Jackal Optimization (GJO) is applied to get the most electrical energy from the PV panels. The output voltage of PV with less switching stress and complexity, a High Gain Interleaved Boost Converter (HGI-BC) has been used. Moreover, a cutting-edge Diamas Multilevel Inverter (DMLI) model is adopted to maximize power quality with reduced harmonics and power loss. Then, the switching components are controlled by a Mayfly Optimized Differential Propagation Controller (MODPC) to improve the power quality performance of the DMLI circuit, and a thorough simulation analysis is carried out in this study to assess the effectiveness of the proposed circuit design. For simulation analysis, the controlling performance and results of the proposed system design are validated using several parameters such as output voltage, current, power, Total Harmonics Distortions efficiency, and voltage stress.</p>
