一种基于模型的直流母线电容离线加速测试监测方法

This letter proposes a model-based monitoring method for the dc-link capacitors in three-phase inverter systems without the need for extra high-performance hardware and intensive computation. By injecting an ac voltage into the dc link and applying the appropriate theoretical analysis, a mathematical model of C can be developed. As the proposed method only requires estimating the parameters from t...
