A Novel Bi-Directional Converter for Low Voltage Motor Drives in Electric Vehicles

The development of the electric vehicles and hybrid vehicles are increasing rapidly due to depletion of fossil fuels, which cause the implementation of new technologies and highly efficient power converters to decrease the dependency on fossil fuels. However, the safety becomes the main issue in the higher voltage level. Therefore, this article is proposed for desirable working, which enhances the usage of low voltage motor drives and improves the safety of the vehicle. The proposed voltage level is 48V, and this voltage is beneficiary for the battery integration and additional source of energies. The suggested bidirectional converter can be operated with input voltage ranging between 12V-48V and wide output voltage ranges with various power level. The presence of additional energy sources in the system aids to enhance the control response necessary during acceleration and braking. Overall, this study proposes a bidirectional converter for connecting vehicles to energy sources and in turn connecting the same converter for connecting energy source to the vehicles.
