摘    要:传统的滞环SVPWM电流控制是一种比较常用的变流器控制策略,它使用角度比较计算和区域选择来实现电流的控制,存在一些误差.因此,提出了一种基于矢量跟踪合成的控制方法,运用坐标旋转思想,取代了角度比较和区域检测.仿真和实验结果表明,这种方法大大减少了网侧谐波含量,同时具有较高的功率因数.

关 键 词:电流控制  跟踪合成  坐标旋转  角度比较

Abstract:Considering the fact that conventional hysteresis SVPWM current control generally employs inverter control strategy,and some errors exist because it controls the current through comparing the calculated angles and the region selection,a vector-based tracking control synthesis control method was proposed to replace both angle comparison and region detection with the thought of coordinate rotation.Both simulation and experimental results show that this method can reduce the harmonic content of the network side and has a high power factor
Keywords:current control  tracking synthesis  coordinates rotation  angle comparison
