Bidirectional DC-DC Converter Fed BLDC Motor in Electric Vehicle

In a world where protection of environment and conservation of energy are giving primary importance, the growth and mercenary of electric vehicle have taken on an accelerated pace. The present and predictable future most importance in the development issue of electric vehicles is how to evolve different energy sources in electric vehicles. Energy source is an important component in an electric vehicle. An appropriate source is competent of delivering power continuously. The type of electric motor and technology of converter impacts a greater significance in regulating the operating characteristics of vehicle. This paper describes a bidirectional chopper fed BLDC motor in electric vehicle. Hence effective cost, weight, volume of converter can be minimised by decreasing the number of switches, sensors, energy storage elements such as inductors. The simulation is performed using MATLAB/ Simulink software and simulation results are presented. In order to validate the functionality, efficiency and performance of bidirectional converter, a prototype has been designed and built.
