摘要
电压空间矢量PWM技术(SVPWM)是从电动机的角度出发,使交流电动机获得圆形磁场,达到较高控制性能的同时也提高了直流电压利用率。其具体实现涉及到三个关键问题,即电压空间矢量所在扇区的判断、基本矢量作用时间的计算、基本矢量的作用顺序及比较寄存器的赋值。针对这三个问题进行了深入的研究,并将有关文献提出的几种方法进行了比较与统一。
The voltage space vector PWM(SVPWM)technique makes the AC motor obtain a circular magneticfield from the point of view of the motor.It achieves a higher control performance and also improves theutilization of voltage.The realization of this technique involves three key problems,namely,the judgment of thesector where the voltage space vector is located,the calculation of the action time of the base vector,theaction order of the base vector and the assignment of the comparison register.These three questions aredeeply studied,and several methods proposed by relevant literatures are compared and unified.
