This paper focuses on fault classification in cascaded H bridge nine-level inverter (CHBMLI). Comparative fault analysis and fault classification are presented. Primitive methods of fault classification like wavelet and principal component analysis were used to classify faults in multi-level inverters. Wavelets were widely used for fault classification as it gives the details of time and frequency information simultaneously. With the advent of neural networks and other soft computing techniques, multilevel inverter fault analysis has become much simpler. Healthy output is compared with faulty signals and this is fed to the neural network. A Neural network trains the signals fed into the network. As a result, the performances of faulty and healthy signals are studied, and results are presented using MATLAB/SIMULINK. [ABSTRACT FROM AUTHOR]
