摘要

The paper conducts the fault diagnosis of three section unequal semi controlled bridge rectifying circuit of electric locomotive in the context of MATLAB/Simulink and suggests the fault analysis method based on the BP Neural Network. Based on the BP Neural Network, it produces failure data by simulation analysis, extracts the character of the faults and constructs the samples of the faults after the normalization processing. This paper also creates network to analyze and recognize the character of the faults and verifies the reliability and practicability of this method by simulation results.
