ntelligent Fault Diagnosis System of Rectifier Circuits
Weihua Gui · Automation and Instrumentation · 2008
This paper analyzes and classifies the different fault modes in the three-phase full-control bridge Rectification,presents the diagnosis method based on wavelet transform and neural network theory,establishes the neural BP network which is corresponded for the output of network,and designs an on-line fault diagnosis system based on DSP.The test result proves the system obtained better effect about the fault diagnosis and the method is correct and feasible.
