Failure Detection Method and Detection Device for Inverter |
| 摘要 |
The present disclosure provides a failure detection method for an inverter, which comprises steps of: performing Fourier transformation on output voltage signals of an inverter to obtain voltage harmonic signals; classifying the Fourier-transformed voltage harmonic signals; and determining a failure type corresponding to the Fourier-transformed voltage harmonic signals. Correspondingly, the present disclosure further provides a failure detection device for an inverter. |
