This research introduces a novel non-isolated, high-gain bidirectional DC–DC converter (BDC) designed to enhance the integration of energy storage systems with electric vehicles (EVs). The proposed converter achieves a high voltage gain through dual duty-cycle operation while utilizing fewer circuit components, resulting in a compact and efficient design. Its dual current-path inductor structure reduces inductor size and eliminates the need for an additional clamping circuit to supply power to the load. Notably, the converter attains substantial voltage gain without relying on voltage multiplier cells (VMCs) or hybrid switched-capacitor techniques. The performance of the proposed converter-based EV drive system is evaluated through simulations conducted in MATLAB/Simulink and Software-in-the-Loop (SIL) testing using OPAL-RT. Various driving scenarios are examined to assess the converter’s operational behaviour. During forward motoring mode, the converter delivers power from the battery to the motor, while in regenerative braking mode, the motor operates as a generator, feeding energy back through the converter to recharge the battery. This bidirectional energy flow enhances overall system efficiency and supports effective energy recovery.
