Abstract

The need for higher power ratings and efficient AC-DC conversion led to opting of Vienna Rectifier for off-board electric vehicle (EV) charging applications. In this paper, a complete analysis of three phase Vienna Rectifier considering the effect of parasitic in the system for off-board EV charging application is discussed. To improve the dynamic response a modified dual loop control using d-axis and q-axis current controller including the effect of system parasitic in control loops is proposed. The proposed algorithm is compared with different control algorithms viz., dual loop control using hysteresis current controller and dual loop control using d-axis and q-axis current controller with SVPWM. A comparative performance analysis is discussed in terms of dynamic response during system disturbances like load variation, reference DC bus voltage variation and grid side variations. A 50 kW Vienna Rectifier operating at a switching frequency of 200 kHz is used for performance evaluation of all three control algorithms and is validated using MATLAB-Simulink.

考虑系统寄生的电动汽车车载充电维也纳整流器设计与分析

对更高额定功率和高效交直流转换的需求导致选择维也纳整流器用于车载电动汽车(EV)充电应用。本文全面分析了考虑寄生效应的三相维也纳整流器在电动汽车车载充电系统中的应用。为了改善系统的动态响应，提出了一种改进的双环控制方法，采用d轴和q轴电流控制器，考虑了控制回路中系统寄生的影响。将该算法与不同的控制算法进行了比较，即使用滞后电流控制器的双环控制和使用SVPWM的d轴和q轴电流控制器的双环控制。从负载变化、参考直流母线电压变化和电网侧变化等系统扰动的动态响应角度，对系统性能进行了对比分析。50kw维也纳整流器在200 kHz的开关频率下工作，用于所有三种控制算法的性能评估，并使用MATLAB-Simulink进行验证。
