Performance Evaluation of Electric Vehicles (EVs) High Voltage Gain Achievement Logic using Bidirectional DC-DC Converter

This paper proposes a new Electrical Vehicle High Gain Achievement Logic (EV-GAL) with a bi-directional DCDC converter employed to realize an energy storage system in electric vehicles (EVs). The new converter is designed to offer a high voltage gain with the control of four duty cycles and a reduced number of elements in the circuit. Its topology adopts dual current path inductor to decrease inductor size, and no additional clamping circuit is needed to provide power to the load. Crucially, this architecture achieves high voltage gain without utilizing any hybrid switched-capacitor approach. The performance of the converter-fed drive system was modelled and simulated with MATLAB/Simulink in different conditions of experimentation. During the forward motoring state, the converter feeds power to the motor from a battery, and the motor gives the power back to the battery through the converter in the regenerative braking mode, which allow for effective power recovery and storage.
