Implementation of New Fault Tolerant Control for Five-Phase Induction Motor in Fault Operation

Abstract

Multiphase electric motors, in conjunction with power semiconductor converters, are the electric drives of the future. This is due to their superior characteristics over three-phase motors. Multiphase motors have a higher fault tolerance, which is one of its benefits. When employing multi-phase motors in EV and HEV, how they perform in a failure condition is critical. And it is on this foundation that the study presented in this paper is based. The article looks at how to regulate a five-phase motor in a fault condition in order to improve the drive's qualities during fault operation. The entire mathematical expressions of the five-phase induction motor model in normal and fault operation are supplied, as well as the control adjustment to improve the drive's attributes. Following that, the five-phase field-oriented control is discussed, which improves the drive's characteristics in four-phase operation.
