摘要
无刷直流电动机脉宽调速系统在制动状态下,其泵升电压会影响整个系统主回路功率器件的可靠性。本文详细地论述了泵升电压出现最大的情况,最后通过实例计算证明。此计算方法也可适用于有刷直流电动机脉宽调速系统。
The pumped voltage of brushless DC motor PWM system can effect the reliability of main loop power devices of whole system in the brake state, this paper discusses in detail when the pumped voltage will emerge maximum in the system, this analysis method can be applied to DC brush motor PWM system.
