摘要
针对SVPWM算法中的扇区判断与相邻矢量作用时间的求取,提出了一种新颖的简单快速算法。新算法摒弃了传统的三角函数和坐标旋转运算,通过比较三相相电压之间的大小关系进行扇区判断,利用线电压进行相邻矢量作用时间的求取,整个过程只需简单的四则运算即可,从而克服了传统算法计算量大影响计算精度的缺点。给出了各个模块和整个系统的仿真模型,仿真结果验证了所提算法的科学性和有效性。
Novel algorithms about sector judgment and function time calculating of adjacent vectors were proposed. The new algorithms did not need any trigonometry function and coordinate transformation. They judged sectors through comparing three phase voltage and calculated function time of adjacent vectors using line voltage. Only simple four fundamental operations were used in the whole process, which overcame the shortcomings of traditional algorithm that has large amount of calculation and affects the calculation precision. Both the modules and the whole system simulation model were given, and the simulation experiment proves that the new algorithms are scientific and effective.
