Single switch open circuit faults in three-phase ACdrives lead to undesired effects and potentially to a total failure of the drive. This paper proposes a post-fault operation strategy for such faults with a focus on the limitation of losses after the reconfiguration and thereby an extension of the possible range of operation. Furthermore, a method for the reduction of alternating torque components during the post-fault operation of a squirrel cage inductionmachine drive is proposed. The performance of the post-fault operation strategy and the alternating torque reduction method are shown both via simulations and experiments.
