Hysteresis current control of Vienna Rectifier for Electric Vehicle Charging Systems

The energy savings, pollution reduction, and environmental protection offered by electric vehicles are superior to those of fuel-powered vehicles. The availability of electric vehicle charging infrastructure is significantly less in India, which is becoming an impediment to the widespread use of electric vehicles due to the range and charging anxieties among the people. Modern power electronic converters play a vital role in electric vehicle charging applications. The output obtained from the converters is harmonic and distorted. The output voltage has to be enhanced to make the PI controller a hysteresis current controller for charging electric cars, and the ripples can be minimized using a Vienna rectifier. There is no harmonic content in the Vienna rectifier at the grid side, which improves the power factor and efficiency. A Vienna rectifier lowers the amount of power that switches use and increases the power density of the system for superior DC charging of electric vehicles. The THD value of the input current can be suppressed to a level below 5%. with the proposed hysteresis current controller and Vienna rectifier. The Vienna rectifier control simulation model is built in MATLAB or Simulink. © (2024) School of Science, DUTH. All rights reserved.
