With the global interests and efforts to popularize electric vehicles (EVs) due to their zero carbon emission, the EV sales are increasing fast in recent years. As key part, the on-board charger (OBC) considerably facilitates the devel- opment of the EV industry by providing the freedom to fueling the vehicle anywhere electricity is available, especially in the metropolitan areas. How- ever, due to the space and weight limitation in an EV, the OBC requires a high power density DC-DC converter transferring the power from a rectified DC-link to the battery pack in the vehicle. The dual active bridge (DAB) con- verter has drawn worldwide attention as a promising candidate for the OBC application. Much research has been done to improve the DAB performance regarding different aspects such as efficiency and reliability. Nonetheless, there are still challenges ahead, which should be addressed to advance the on-board charging.
