Performance Evaluation and Analysis of the CMLI fed PMSM with Various Fault Conditions

Fault diagnosis in Multilevel Inverters (MLI) has taken worthwhile attention into account in this era. Researchers, Scholar, Engineers and Scientist are paying august attentions towards fault diagnosis in multilevel inverter they are also ascertaining new methods and techniques to diagnose accurate faults in minimum time. To develop fast and precise detection to make system more reliable and efficient, the performance evaluation of the drive under different fault conditions is required. This paper presents a detailed performance analysis of the Cascaded H-bridge Multilevel Inverter (CMLI) fed Permanent Magnet synchronous Motor (PMSM) under different fault (single and multiple switch faults) conditions. It will help to design a fast and accurate fault diagnosis technique to prevent the system failure.
