Abstract:

在电力机车牵引传动系统中,受到最高开关频率以及输出电压、电流谐波性能的限制,通常需要采用特殊的优化脉宽调制策略。其中,电流谐波最小PWM(currentharmonicminimumPWM,CHMPWM)可以使电机电流谐波分量总体最小,从而有助于提高电机控制性能,减小系统损耗,降低开关管的电流应力,而受到越来越多的关注。对不同开关角个数下CHMPWM的开关角随调制比的分布进行计算,之后以异步电机为例,以加权总谐波畸变(weightedtotalharmonicdistortion,WTHD)和单次电流谐波幅值为指标对CHMPWM的电流谐波性能进行了理论分析,并与特定次谐波消除PWM(selectedharmoniceliminationPWM,SHEPWM)
