Description
Summary:This research presents a novel non-isolated high gain bidirectional DC-DC converter (BDC) and its application in integrating energy storage system with electric vehicle (EV). The proposed converter can provide high voltage gain with the help of two duty cycle operation by employing fewer components in its circuit design. The proposed topology makes use of dual current path inductor structures which reduces their size and eliminates the need for an additional clamping circuit to power the load. Without using voltage multiplier cells (VMC) or hybrid switched-capacitor approaches, the proposed converter can achieve a significant voltage gain. The simulation of the proposed converter-based drive is carried out using MATLAB/Simulink and OPAL-RT software in loop (SIL) system and the performance analysis is done for different driving conditions. The converter powers the motor through the battery during the forward motoring mode. The motor acts as a generator during regenerative braking and the energy is transferred back through the converter to the battery which stores the recovered energy.
