摘要
传统SVPWM算法需要扇区判断和繁琐的三角函数运算,且所有的基本电压矢量必须预先计算并储存起来供后续运算调用,既增加了控制器的计算量,又占用了一定的存储空间。为此,提出一种通用简化空间矢量调制法,先定位参考电压矢量的位置,并找出顶点矢量,再基于两个表格进行简单的逻辑运算即可得到所需的开关状态和开关顺序。仿真和实验结果验证了算法的有效性和通用性。
Traditional SVPWM algorithm needs the sector judgment and complex trigonometric operation. And all of the basic voltage vector must be pre-computed and stored for subsequent call, not only increases the controller＇s workload, but also occupy a certain amount of storage space.Therefore, a simplified space vector modulation is pro- posed. Firstly, locating the reference vector, and finding the vertex vector. Then it can get all the required switch states and switch sequence based on simple logic operation of two tables. Simulation and experiment results verify the effectiveness and generality of the proposed algorithm.
