A STRATEGY TO ISOLATE A SWITCHING DEVICE FAULT IN A CURRENT REGULATEDMOTOR DRIVE

In this paper a new, improved induction motor control topology is prop osed which allows for continuous, disturbance-free operation of the dr ive with a failed short-circuited switch in one leg of the inverter. T he analysis of this control strategy and the computer simulation are e xplored. The experimental results from hardware are attached to verify the simulation results. A complete control strategy combined with sho rt-circuit fault and open-circuit fault is also included.
