ZHAO Qiang, GUO Yuhua, TIAN Yongzhu, et al. State Data Simulation of Traction Converter for EMUs[J]. Electric Drive for Locomotives, 2016,(2):5-8. DOI: 10.13890/j.issn.1000-128x.2016.02.002.
In order to solve the defects of traditional EMUs traction converter maintenance mode, converter prognostic and health management technologies were introduced. The principle of the fault diagnosis of prognostic and health management of traction converter based on HMM model and wavelet analysis method was discussed, and the MATLAB simulation model was built and researched, which verified the feasibility of the methods.
