Fault Diagnosis and Fault-Tolerant Operation of Multi-Level Power Converters - Presentation

Occurrence of switch faults is common in multi-level converters. Marquette University develops and verifies an effective fault diagnosis method and the related fault-tolerant control strategy for switch faults in multi-level converters using ANSYS Simplorer. The study investigates negative impacts of the switch faults on the permanent magnet machine at the load end through cosimulations using ANSYS Simplorer and ANSYS Maxwell.
