| 摘 要： | 介绍了三相电压型PWM整流器(VSR)的拓扑结构和电压定向控制(VOC)的基本原理。针对三相VSR传统中电压空间矢量(SVPWM)算法的缺陷性,提出了一种优化SVPWM调制方法。该方法利用电压空间矢量旋转的幅角来判断扇区,并由相电压的电压差值计算基本电压矢量的作用时间,完全省略了坐标变换和三角函数计算,化简了SVPWM算法步骤。经过MATLAB/SIMULINK建立电压定向控制(VOC)仿真模型,可以证明该优化SVPWM算法的正确性,为改进三相VSR的硬件设计提供了依据。

| Abstract: | The topology of three-phase voltage-source PWM rectifier(VSR) and the basic principle of voltage oriented control(VOC) were presented.Given the shortage of the traditional space vector pulse width modulation(SVPWM) algorithm applied in three-phase VSR, this paper puts forward an optimized SVPWM, by which the sector can be judged according to the rotating argument of voltage space vector, and the function time of basic voltage vector can be calculated based on the 3 phase voltage difference computation.Compared with the former two methods, the coordinate transformation and trigonometric calculation are completely omitted and the algorithm steps are simplified in the optimized SVPWM.The validity and practicability can be verified through the simulation of VOC system with MATLAB/SIMULINK. |
