In the proposed research, a 3.3 kV reverse-blocking (RB) device, one of the key components in the M-S4T, is fully characterized. A unique voltage sharing phenomenon within the RB device is analyzed and the guidance of using this device in the M-S4T is provided.\u0026nbsp; In addition, a decoupled quasi-real-time (QRT) model of the M-S4T is proposed for hardware-in-loop (HIL) simulation and the accuracy of the QRT model is verified experimentally. To control the M-S4T, a control architecture for synchronization and communication between each modules is proposed and the proposed control architecture is verified by HIL simulation on OPAL-RT platform.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Soft-Switching Solid-State Transformer for Traction Applications"}],"uid":"28475","created_gmt":"2019-09-04 21:56:35","changed_gmt":"2019-09-09 18:23:49","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-09-16T10:00:00-04:00","event_time_end":"2019-09-16T12:00:00-04:00","event_time_end_last":"2019-09-16T12:00:00-04:00","gmt_time_start":"2019-09-16 14:00:00","gmt_time_end":"2019-09-16 16:00:00","gmt_time_end_last":"2019-09-16 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"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":""}}}
