摘要
本文利用电压空间矢量的概念,提出了气隙旋转磁场磁通轨迹的几何逼近方法,以此来确定逆变器PWM的切换时刻,并与传统的正弦波调制方法作了比较。实验结果表明本方法直观,易于用8位单片机实现。
Using the space voltage vector concept, an approach method of flux linkage locus created by the PWM inverter for deriving the switching instants is presented. It is compared with SPWM method. The experimental results show that it is suitable for 8-bit single-chip microcontroller implementation.
