摘　　要：利用VIENNA整流器的数学模型,分析了基于电压定向空间矢量脉宽调制(SVPWM)控制策略和基于物理解耦的单周期控制策略。在MATLAB/Simulink环境下,对两种控制策略分别建立了仿真模型,并对结果进行了比较分析。最后通过搭建1. 5 kW试验样机,对SVPWM控制策略和单周期控制策略进行了试验验证比较。结果表明,SVPWM控制策略具有更低的高次谐波,是一种更理想的控制方法。Based on a mathematical model of VIENNA rectifier,this paper analyzed the control strategy based on voltage-oriented space vector pulse width modulation（SVPWM） and the single cycle control strategy based on decoupling in topology. In the MATLAB/Simulink environment,a simulation model was established for the two control strategies respectively,and the results were compared and analyzed. Finally,a 1. 5 kW experimental prototype was set up to make experimental verification and comparison for these two control strategies. Experimental results demonstrated that the SVPWM control strategy with lower ultra-harmonics was a more ideal control method.
