摘要
针对电平数目较多的多电平逆变器在空间矢量调制时出现的空间矢量定位困难和计算量大的问题,提出了一种将坐标轴沿坐标原点顺时针或逆时针旋转45°的快速空间矢量调制算法。仿真结果表明该算法具有快速性,易于实现,电路输出的电压相量轨迹基本逼近标准圆,输出电压谐波较少。
As the number of level increases, the difficulty of making the appropriate vector selection in multilevel inverter is a large amount of computation. In order to solve the problems, a new arithmetic based on making rotate of the axis of 45 （clockwise or anticlockwise） is presented. By simulation, it is found that the arithmetic has lots of merits, such as making the appropriate vector very fast and the output voltage vector track approaching standard circle.
