Design and Development of Bidirectional DC–DC Converter for Electric Vehicle Application
摘要
This paper describes the design and implementation of a bidirectional DC–DC converter for Electric Vehicle (EV) applications. The bidirectional converter facilitates effective energy transmission in both directions among the low-voltage DC bus and the high-voltage Battery. The key objective of this research is to optimize the converter's charging and discharging of batteries to fulfill the specifications for modern EVs. The duty cycle and voltage gain of the proposed converter are compared to conventional converters. To achieve low switching losses and reduced power dissipation control strategies with PI Controller is thoroughly investigated. To evaluate the converter's performance in both steady-state and dynamic operating scenarios, a closed loop simulation model has been developed and tested. Furthermore, as an application of these converters, the concept of bidirectionality charge and discharge of battery is analyzed using MATLAB/SIMULINK software.
