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.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"ECE Proposal Oral Exam"}],"uid":"28475","created_gmt":"2016-03-08 18:44:11","changed_gmt":"2016-10-08 02:16:55","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-03-15T12:00:00-04:00","event_time_end":"2016-03-15T12:00:00-04:00","event_time_end_last":"2016-03-15T12:00:00-04:00","gmt_time_start":"2016-03-15 16:00:00","gmt_time_end":"2016-03-15 16:00:00","gmt_time_end_last":"2016-03-15 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"1808","name":"graduate students"},{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
