Integration of AC/DC With Multi Input Mode Selection Converter for Fast Charging of Battery in Electric Vehicles

Transportation must be rapidly electrified, including recharge infrastructure expansion, to keep up with the fast growth of electric vehicle technology. As the power levels handled by DC fast converters for electric vehicles rise, there are fresh hurdles for switching devices to adhere to efficiency standards. The present research introduces a novel multi-input mode selection converter (MI-MSC) that combines the AC grid and auxiliary battery as input sources to provide a constant current of 15A. This current range is essential in hybrid energy applications, especially fast-charging electric vehicles. The converter uses up to five switches to control the power flow between the two input ports. Simulink MATLAB simulates the proposed system with a fuzzy logic controller that can charge the battery in Constant Current (CC) charging and perform power factor correction (PFC). In addition, it is used to select various operating modes based on load requirements. The OPAL-RT 5700 tests and validates real-time hardware in-loop (HIL) performance. The system successfully meets the load demand across different load scenarios, manages power efficiently, and evaluates the total harmonic distortion (THD) level.
