Redundant Technique used in VSI Topology

The industrial applications consists of a power electronic converter, and a digital controller for implementing the control algorithms, motor and a feedback sensors,. Several faults can affect on the motor drive and also it affects the whole system and some critical applications such as power plants, railway locomotives, aerospace, automobiles, etc., here main important thing to avoid fault tolerance. In this project work, redundant technique used in VSI topology fed AC motor simulation models is discussed and simulation models are developed using MATLAB Simulink tool box. The performance studies are used to simulated models and to obtain the results in the form of asynchronous motor. An analysis of the performance of these drives under various faulty conditions has been presented. The investigation of redundant control techniques for AC motor drives is arousing lively interest, since it can extend their use to applications where high reliability is a key feature, such as automotive auxiliaries and aircraft.
