文中研究了60°坐标系下SVPWM一种新算法,通过3个基本矢量的开关状态函数根的个数来确定每个基本矢量的类型即零矢量、小矢量、中、大矢量.无需判断大扇区以及矢量作用时间复杂的分配,简化了计算.Matlabsimulink仿真结果表明了该算法有效性.%A new method for SVPWM based on 60° coordinate system is presented in the paper,to define the type of each basic vector such as zero vector、small vector、middle vector and big vector by the number of root of a function of switch state of three basic vector.There is no need to determine the big sectors and the complex distribution of the action time of the basic vector.It simplifies the calculating burden.The results of simulation show that the new method is effective.
