Abstract: ABSTRACT This project implements a hybrid electric vehicle system with a novel bidirectional DC-DC converter (BDC) that interfaces between the main energy storage (ES1), auxiliary energy storage (ES2), and DC bus at different voltage levels. The proposed BDC can operate in both step-up and step-down modes. The step-up mode represents a dual low voltage source powering mode, while the step-down mode represents a high voltage DC link energy-regenerating mode. Both modes are controlled for bidirectional power flow. This model can independently control power flow between the dual low voltage source buck/boost modes. The circuit configuration, operation, steady-state analysis, and closed-loop control of the proposed BDC are examined according to its three power transfer modes. A fuzzy logic controller is implemented and the system results are validated through MATLAB/SIMULINK software. Index Terms—Bidirectional dc/dc converter (BDC), dual battery storage, hybrid electric vehicle, Fuzzy logic controller.
