摘要
为了提高永磁同步电机母线电压利用率,减小电压矢量合成角度偏差,提出了一种基于电压比例缩放谐波注入式脉宽调节方式.谐波注入采用查表式,以减小电流环计算时间,提高电流响应速度.采用电压比例缩放的脉宽调制方式,消除了传统脉宽调制限幅造成的电压矢量计算角度偏差.仿真及实验结果表明,该种脉宽调制方法提高了母线电压利用率,有效抑制了传统脉宽调制方法的电压矢量计算角度偏差,提高电机在高速旋转工况下的电流响应特性.
In order to raise the utilization ratio of permanent magnet synchronous motor bus voltage,and reduce the voltage vector angular deviation,a method with harmonic injection pulse width modulation was proposed based on voltage ratio zoom.In harmonic injection with look-up table type,it was taken as advancing the current respond rate to reduce the harmonic value computation time.A pulse width modulation method of voltage ratio zoom was utilized to eliminate the calculation deflection of voltage vector,and raise the utilization ratio of the bus voltage.The simulation and experimental results show that this kind of pulse width modulation can improve the utilization ratio of the bus voltage and motor response ability under high speed command.
