Abstract
The paradigm shift toward electric transportation is a necessary step in mitigating greenhouse gas discharges in connection with the internal combustion engine emissions. Nevertheless, the Electric Vehicle (EV) charging infrastructures predominantly rely on fossil fuel-based power generation, which again aggravates climate change. Imparting renewable energy sources for powering the charging systems is therefore essential, with photovoltaic (PV) power standing out as a scalable and portable solution. In PV-based charging setups, the power available from the panels can vary widely, especially when some modules fall under shade. To keep the charging process steady during such conditions, a smarter MPPT approach becomes necessary. In this work, a single-stage full-bridge converter operating with phase-shift control is combined with an Social group optimization based MPPT method to improve…
