Fault diagnosis simulation study of cascaded converter based on wavelet packet neural
摘要
Abstract
The power component open circuit faults diagnosis method of a cascaded converter is mainly stud- ied. According to the output voltage signal features of a frequency-domain, an energy eigenvector was estab- lished by the means of a wavelet packet. Then fault pattern recognition of the cascaded converter was presen- ted using BP neural network. The result shows that wavelet packet neural network in the cascaded converter fault diagnosis has high feasibility and validity.关键词
