A Novel Investigation on Single-Input Three-Output DC-DC Buck Converter For Electrical Vehicles

In present era, efficient electrical vehicle (EV) design is an ever-increasing interest to the industry and academia. The research work carries a novel investigation on Single-Input Three-Output DC-DC Buck Converter for converting single DC voltage input to multi-output DC voltage levels in EVs. The proposed convertor topology is a non-isolated bidirectional DC-DC Buck converter with a single input of 48V and multi-outputs 12V (for Horn) and 5V (for telemetry). In addition, the investigation has been carried on the performance of Single-Input to Three-Output level DC-DC Buck converter. The proposed research work also presents model operation, design specifications, and stability analysis and control strategies. The performance of the proposed converter topology has been simulated in MATLAB/Simulink environment and the results are computed. The results show that the proposed convertor topology reduces the cost and switching losses and also enhances the efficiency, reliability and availability of proposed converter.
