Fault-tolerant cascaded H-bridge converter for an induction motor drive

摘要

In this paper an induction motor drive system based on a fault-tolerant cascaded H-bridge converter is presented. The proposed system is composed by an induction motor fed through a 13-level cascaded H-bridge converter. In this case a neutral shift method has been implemented for the CHB converter in order to make it fault-tolerant. The proposed system has been modelled and tested in Matlab-Simulink.
