Fault Diagnosis for Power Electronics Converters based on Deep Feedforward Network and Wavelet Compression. (arXiv:2211.02632v1 [eess.SP])

A fault diagnosis method for power electronics converters based on deep
feedforward network and wavelet compression is proposed in this paper. The
transient historical data after wavelet compression are used to realize the
training of fault diagnosis classifier. Firstly, the correlation analysis of
the voltage or current data running in various fault states is performed to
remove the redundant features and the sampling point. Secondly, the wavelet
transform is used to remove the redundant data of the features, and then …
