Abstract

Compared with the discrete structure of traditional On-Board Chargers (OBC) and Low-voltage DC Converters (LDC), this paper proposes an isolated three-port OBC topology, which uses a multi-winding transformer to achieve magnetic coupling between three ports, which effectively improves power density. Functionally, it realizes the functional integration of OBC and LDC, which can meet the requirements of use under a variety of working conditions. This paper reasonably designed the control strategy under each mode, and finally verified the feasibility of the design scheme based on MATLAB/simulink.
