Qualitative and Quantitative Models Used for Faults Diagnosis of Power Converters

Fault Diagnosis for Engineering Systems gives a complete presentation of basic essentials of fault diagnosis, and takes a look at the cutting-edge discipline of intelligent fault diagnosis for condition-based maintenance. The paper presents a defect detection system based on development the tree faults analysis for a power rectifier. The tree fault method is used for quantitative and qualitative analysis of system reliability. For the qualitative analysis of the faults, the tree of faults is developed, based on symptoms, considered to be the most frequent ones during the operation of the power rectifiers. The paper describes the steps of the diagnostics system and the results obtained after the quantitative and qualitative analysis with the tree fault method for the three phase power rectifier.
