Design and Control of Level-1 Battery Charging by Using DAB Converter

An electric vehicle (EV), which is widely used and the battery is key device. The battery used in the EV is chargeable battery which is the main advantage of EV. So, this battery is charged by the on-board charger or off-board charger. Bidirectional dc-dc converters are used for this and one of them is Dual Active Bridge (DAB) converter. Modulation technique used in this paper is single phase shift (SPS). The battery charging by the constant current (CC) mode with the help of PI controller and implemented in the MATLAB Simulink platform.
