Abstract

Electric vehicles (EVs) could be used to address the issues of environmental pollution and the depletion of non-renewable energy resources. EVs, which are energized by a battery storage system, are becoming attractive because they keep the environment clean. Furthermore, the cost of EVs is becoming cheaper. Thus, EVs will become a significant load on utility distribution system in the future. EV chargers play a significant role in the expansion of EVs. The input current of an EV charger with a high total harmonic distortion (THD) and a high ripple distortion of the output voltage can impact battery life and battery charging time. Furthermore, the high cost and large size of the chargers are considered other issues in EV development. This work presents the complete design process of a universal EV charger with a special focus on its control algorithms. In this regard, a novel control algorithm based on the integration of voltage-oriented control (VOC) and the sinusoidal pulse-width modulation (SPWM) technique is proposed to ensure effective Levels 1, 2, and 3 battery charging. A simulation of the universal EV charger was conducted and assessed in MATLAB–Simulink. Moreover, a laboratory prototype was constructed with a TMS320F28335 digital signal processor (DSP) programmed as the controller to validate its operation and performance. The findings show that the proposed charger is able to provide a controllable and constant charging voltage for a variety of EVs, with an input current of low total harmonic distortion (THD) and an almost unity power factor.

Summary

Introduction

Most of the vehicles in the transportation system are still dependent on liquid fossil fuels, which are slowly being depleted. Was sufficient in providing a utility with reactive power support and other vehicle-to-grid benefits, The method able to operate with different voltage/frequency values while maintaining a lower but MPC the work did is not study the grid-to-vehicle (G2V). Technique is proposed to support control the converters benefits, but the work did not study the grid-to-vehicle of the EV charger These stages are a pulse-width modulation (PWM) rectifier, sinusoidal. VOC technique demonstrates with their respective reference values to generate gating PWM pulses for controlling the switching highly dynamic appropriate output voltage, and a low THD of the input current. The charger system is designed with three stages of converters: A PWM VOC rectifier, SPWM inverters, and a diode bridge rectifier These provide the results of a unity power factor at the input stage, and the total harmonic distortion (THD) of the input current is approximately 0.83%. The final section concludes and highlights the important contributions of this work
