摘要：
This article proposes the new multifunctional integrated dc-dc converter (MFID), which performs all functions of on-board charger (OBC) and low-voltage dc-dc converter (LDC) for electric vehicles. The proposed MFID reduces the total number of components, while satisfying all operating requirements such as bidirectional operation, wide voltage range, high efficiency, etc. In other words, it successfully charges a high-voltage battery (HVB), supplies the energy of HVB to grid, and charges a low-voltage battery without additional converters and complex control, which are required by the conventional OBC-LDC integrated dc-dc converters, while increasing the efficiency and reliability of converter. The adaptive operation and design specification of the proposed MFID are first analyzed. Then, its practical effectiveness is verified by experimental tests on a hardware prototype of 2.2 kW.
