Abstract
Abstract
In this manuscript, an enhanced performance of Electric Vehicle (EV) charger (battery) by adopting Bridge Less (BL) Cuk converter and Artificial Bee Colony (ABC) algorithm is investigated. Minimum numbers of switches are employed in this proposed methodology to charge the battery with optimum cost. Steady state input voltages and currents are obtained even though the EV charger operates with unbalanced load i.e. operated in underload, nominal load, or overload. It maintains constant battery parameters even under unbalance in input supply also. Robustness is achieved by operating BL-Cuk converter with ABC algorithm even with variation of 50% rise or decay in input voltage. Proposed technique utilizes reduced number of switches, so conduction losses are less and no need of DC link capacitor. Hence, balance voltage appears across the capacitor over the conventional EV charging approaches. Fly back converters are introduced to synchronize the AC supply, Cuk converter and EV charger.
