Abstract
The integration of electric vehicles (EVs) is becoming vital for both the transportation and energy sectors. At the same time, they need an appropriate charging facility. Photovoltaic (PV) powered electric vehicle chargers are gaining popularity since they require negligible maintenance and steadily enhance the efficiency of PV modules. In this paper, a grid tied solar PV with a 12 pulse Line Commutated Converter (LCC) based off board EV charger is presented. The specialty of the proposed method is that it does not require an extra controller for ac grid synchronization. In addition, simplified maximum power point tracking (MPPT) control is proposed, which will track the MPP of the PV array. The main disadvantage of LCC is its poor harmonics profile, which can be improved by a higher pulse number with adequate phase shift. With 12 pulse LCC, high characteristics harmonics are greatly reduced. The performance and efficacy of the suggested method have been confirmed by simulation, which proves the feasibility of the proposed solution for EV charging in both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) modes.
