Abstract: To solve the open circuit faults of the switching device in multilevel inverters, a fault diagnosis and fault-tolerant control strategy was proposed for a cascaded H-bridge multilevel inverter. The fast fourier transform(FFT)and the principal component analysis(PCA)were utilized to reprocess and feature extraction respectively without changing the circuit topology of the cascaded H-bridge multilevel inverter. The faults of cascaded H-bridge multilevel inverters could be fast diagnosed with constructing Bayesian network(BN). According to the fault diagnosis results, output voltages of the multilevel inverter could still meet the demands to keep the system operating smoothly. The way was based on a voltage reconstruction fault tolerant control method by changing the modulation waves and carrier waves, and the performance of the strategy was verified by simulation and experiment.

Key words: multilevel inverters, voltage reconstruction fault tolerant control, fault diagnosis
