Abstract :
Electric vehicles (EVs) rely heavily on efficient power conversion systems to manage energy between the battery and the motor. Therefore, this paper proposes an evaluation of a high gain bidirectional DC-DC converter integrated with a DC drive system, featuring regenerative braking capability for EV applications. Proposed System includes a high gain bidirectional converter based on a Zeta Boost topology, enabling effective power flow between the battery, DC drive, and grid. During motoring mode, energy from the battery is directed to the load (DC drive) through the converter, ensuring sufficient propulsion power. In regenerative braking mode, the kinetic energy of the vehicle is recovered and converted back to electrical energy, which is then stored in the battery, enhancing overall system efficiency. A single phase voltage source inverter (VSI), driven by DSP based PWM signals and isolated via driver circuits, enables bidirectional power transfer to and from grid. Controllers maintain constant DC link voltage, regulating drive current, and managing power balance. The LC filter at the inverter output ensures smooth grid interfacing by reducing harmonics. This integrated system not only improves energy recovery during braking but also provides stable operation under varying load conditions, contributing to enhanced energy management and drive performance. This novel approach is implemented by using MATLAB/Simulink and attains enhanced converter efficiency of 98.28% and voltage gain of 15.4%, respectively.
