N2 - This article introduces a new isolated, three-port, bidirectional DC-DC converter topology for EV APM. Through the manipulation of duty cycles and phase shifts between the LV and HV sides, the proposed topology achieves DCX at bridges 1 and 3, as well as near DCX at bridge 2, leading to a significant reduction in switching losses. Moreover, by controlling the phase shift between bridge 1 and bridge 2, the circulating current is halved, resulting in an overall 2% increase in efficiency compared to the existing configurations. A laboratory prototype of the three-port APM, featuring 140kHz operation and a wide voltage range of 400V to 840V has been implemented to validate the proposed structure.
