数字脉宽调制方法的研究

摘要

Based on introduction of the integrated DSP motor controller ADMC331 and its PWM controller, this paper made analysis and comparision of the single and double digital PWM modes, and put forward the basic principles on the choice of the criterion of the PWM modes.Finally, it gives the corresponding results of the experiment that is done on a three-phase ACmotor voltage source inverter.%借鉴集成DSP电机控制器ADMC331及其PWM控制器结构，对单边和双边数字脉宽调制方式进行了比较，提出了脉宽调制方式选择的基本原则，以三相交流电机电压型逆变器做实验研究，得出了相应的实验结果.
