摘要
本文先采用变异型SPWM调制模式使谐波电压降到最低度,进而再借助于电机定子绕组期望数据,再度使电机气隙谐波磁势削弱,从而使电机气隙合成磁势基本接近正弦波。初步分析结果表明,不仅该系统的调节特征将接近线性特征,而且它能明显简化微机的软硬件。
Applying variant SPWM modulation method,the harmonic voltage may drop to the lowest,and then the air-gas harmonic magnetic potential of the electric machine is weakened by electing the appropriate expected data of the stator winding of electric machine. So the compound air-gas magnetic potential is approaching sinusoidal wave. This method can apparently simplify the hardware and saftware of microcomputer and increase the control accuracy.
