Title: Control of the DC-AC and AC-AC Modular Multilevel Converters under Abnormal Conditions
Committee:

Abstract: The objective of the proposed research is to address the open-switch failure detection/location and post-fault operation of the MMCs. The proposed research includes: (1) dynamic and steady-state models of the MMCs to calculate their internal variables under normal and SM failure conditions; (2) open-switch failure detection methods; (3) post-fault strategies and corresponding circulating current suppression methods subsequent to bypassing the faulty SMs; (4) post-fault strategies when the converter is subjected to input-side abnormalities.
