FILTER CAPACITOR DEGRADATION DETECTION APPARATUS AND METHOD |
| 摘要 |
Power conversion systems and methods are presented for detecting input filter capacitor degradation or approach of end of operational life based on filter capacitor current measurements using single and/or dual threshold comparisons for computed instantaneous sum of squares of filter currents or power values. |
