This research paper discusses a bidirectional DCDC fast charger (or level-3 charging system) to obtain a highpower level. However, two types of EV charging systems are available, i.e., an on-board charging system and an off-board charging system. For dc fast charging, it is essential to use the off-board charger to reduce the volume and weight of EVs significantly. This charger charges the EV battery using a Dual Active Bridge (DAB) topology for the DC-DC converter, which is better for bidire...
