| 摘 要： | 提出了基于数字信号处理器TMS320F240的一种空间矢量PWM算法。通过预分解矩阵，由期望电压矢量直接计算空间矢量在各个扇区内的作用时间。该算法不需要正弦函数和反正切函数查表，故程序运算速度和控制精度明显提高，对提高开关频率、提高PWM整流器的功率密度有重要意义。文中还给出了一种判别扇区的方法，仿真和实验结果验证了该算法的有效性。

| Abstract: | A novel a lgorithm for space vector pulse width modulation in three phase power factor cor rection applications is proposed. Time durations for the active vectors formed b y the sector containing the desired reference voltage vector are directly calcul ated by matrix pre-decomposing, without looking up sinusoidal and tangential ta bles, based on TMS320F240. Therefore running speed and control precise of the pr ogram can be improved. As a result the switching frequency and power density of the rectifier are increased. A new method for detecting the sector is given. Fin ally simulation and experimental results are given to verify the algorithm. |
