A Simple, Fast and Robust Open-phase Fault Control Strategies for Five-Phase Induction Motor Drives with Parallel Converters without Common Mode Voltage

Open-End Winding Five-Phase Induction Motor (OEW-FPIM) are employed in applications where the reduction in the total power per phase and the highest level of overall system reliability is required, where a self-starting and operation under open phase(s) stand as the most salient features. This paper presents a simple, fast and robust open-phase fault control strategies for OEW-FPIM using parallel converters without common mode voltage: field-oriented control and backstepping control. The awaited goal is to evaluate the proposed approaches which give the best performance under open phase fault conditions. The performance of the two control approaches verified and compared by simulation. Provided tests analyze steady and transient states, including an open-phase fault condition. Obtained results prove the interest of the proposed approaches, which ensures the open-phase fault-tolerant capability of FPIM drives with parallel converters.
