摘要
电压空间矢量控制通常应用到三相感应电机的控制中,针对四开关逆变器拓扑空间矢量PWM进行研究,并应用于感应电机控制当中。由于仅存在四个基本电压矢量,不存在零矢量,控制方案有其特殊性。仿真及试验的结果证明,该方法是切实可行的。
Space-voltage vector control strategy is often used in 3-phased induction motor. A space-voltage vector method is researched with four-switch inverter. Because the method has only four basic space-voltage vectors and no zero vector, the control path is different from the general structure. Results of simulations and experiments indicated that the method is reliable.
