Fuzzy Based Open Switch Fault Diagnosis of Three Phase Voltage Source Inverter

The fault diagnosis and subsequent remedial actions require human interleaving at every step. In a number of circumstances, the chance of a fault occurring is imprecise and incompletely specified. During condition-based monitoring, the maintenance engineer must use intelligence to make realistic decisions based on a large amount of data. On one hand, fault diagnosis problems are based on information, while on the other, they are based on rules. This is a challenging opportunity to apply Fuzzy Logic theory and concepts to the fault diagnostic process. The methodologies to defect diagnostic systems based on Wavelet Transform and Fuzzy Logic are presented in this study.
