摘要
介绍了一种基于双脉冲更新方式的死区补偿方法,根据电流极性,在每个PWM周期两次改变占空比时间,补偿死区效应造成的影响。并将此方法应用在以ADMCF328型DSP为核心的感应电机控制系统中,实验波形证实了该方法的有效性。
A dead time compensation method based on double update mode was presented. In order to compensate the side effect of dead time, this method changed the duty cycle twice every period according to current polarity. The proposed method was implemented in a DSP （ADMCF328） based induction motor control system, and the experiment waveforms proved its validity.
