This paper proposes a fault detection and the improved fault-tolerant control for an open fault in the five-phase inverter driving

system. The five-phase induction machine has a merit of fault-tolerant control due to its increased number of phases. This paper

analyzes an open fault pattern of one switch and proposes an effective fault detection method based upon this analysis. The

proposed fault detection method using the analyzed patterns is applied in the power inverter. In addition, when the open fault

occurs in the one switch of the induction machine driving system, the proposed fault-tolerant control method is used to operate

the induction machine using the remaining healthy phases, after performing the fault detection method. Simulation and experiment

results are provided to validate the proposed technique.
