一种基于间歇性反向充电控制策略的电机驱动系统直流母线电容在线估计方法

The dc-link capacitor in the three-phase ac–dc–ac motor drive system is a critical component. The degradation of dc-link electrolytic capacitors is a common failure that has a significant impact on system reliability, which can often lead to system breakdown or damage. It is significant to provide monitoring and prognostic techniques for dc-link capacitors to assist in preventive maintenance. To r...
