Open-Circuit Fault Diagnosis and Fault- Tolerant Model Predictive Control of SubMultilevel Inverter Conference Paper uri icon


  • © 2018 IEEE. This paper proposes a simple open-circuit fault diagnosis and fault-tolerant control approaches for a 15-level submultilevel inverter (SMI). The proposed strategy uses a model predictive control (MPC) to regulate the output current. The fault and its location are detected by comparing the total harmonic distortion (THD) level of the inverter output voltage with the predefined performance metrics. The proposed fault-tolerant control algorithm reconfigures the switching states of the inverter according to the location of fault. Experimental investigations are conducted to show that the proposed control strategy exhibits a good performance in achieving the required control objectives in case of open-circuit faults.
