The DC-DC MMC has subsequently been proposed\/derived based on the DC-AC MMC concept, borrowing its salient features for medium-\/high-power DC-DC conversion.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EHowever, the operation and control challenges for the DC-DC MMC are fundamentally different from those for the DC-AC MMC. As opposed to the DC-AC MMC, proper operation of the DC-DC MMC necessitates injection of AC circulating currents within the legs. However, those circulating currents deteriorate the efficiency and increase the size of submodule capacitors and rating values of the switching devices, thereby increasing the footprint and cost. The paper presents novel control strategies to inject the minimum AC circulating currents such that proper operating of the converter is guaranteed while the converter efficiency and power density is maximized.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ERecent\u0026nbsp;ECE Ph.D. graduate\u0026nbsp;Heng Yang and his doctoral\u0026nbsp;advisor Maryam Saeedifard have been selected for\u0026nbsp;the\u0026nbsp;IEEE Industrial Electronics Society Best Transactions Paper Award.\u0026nbsp;\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Recent\u00a0ECE Ph.D. graduate\u00a0Heng Yang and his doctoral\u00a0advisor Maryam Saeedifard have been selected for\u00a0the\u00a0IEEE Industrial Electronics Society Best Transactions Paper Award.\u00a0"}],"uid":"27241","created_gmt":"2018-06-27 17:25:28","changed_gmt":"2018-06-27 17:25:28","author":"Jackie Nemeth","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2018-06-27T00:00:00-04:00","iso_date":"2018-06-27T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"607338":{"id":"607338","type":"image","title":"Heng Yang","body":null,"created":"1530118800","gmt_created":"2018-06-27 17:00:00","changed":"1530118800","gmt_changed":"2018-06-27 17:00:00","alt":"photograph of Heng Yang","file":{"fid":"231663","name":"Heng_Yang_Photo.jpg","image_path":"\/sites\/default\/files\/images\/Heng_Yang_Photo.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/Heng_Yang_Photo.jpg","mime":"image\/jpeg","size":393006,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/Heng_Yang_Photo.jpg?itok=DuJCq24d"}}},"media_ids":["607338"],"related_links":[{"url":"http:\/\/www.ece.gatech.edu","title":"School of Electrical and Computer Engineering"},{"url":"http:\/\/www.gatech.edu","title":"Georgia Tech"},{"url":"https:\/\/ieeexplore.ieee.org\/xpl\/RecentIssue.jsp?punumber=41","title":"IEEE Transactions on Industrial Electronics"},{"url":"http:\/\/www.iecon2018.org","title":"2018 IEEE Industrial Electronics Society Conference"}],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[{"id":"129","name":"Institute and Campus"},{"id":"130","name":"Alumni"},{"id":"134","name":"Student and Faculty"},{"id":"8862","name":"Student Research"},{"id":"135","name":"Research"},{"id":"144","name":"Energy"},{"id":"145","name":"Engineering"}],"keywords":[{"id":"178424","name":"Heng Yang"},{"id":"137611","name":"Maryam Saeedifard"},{"id":"109","name":"Georgia Tech"},{"id":"166855","name":"School of Electrical and Computer Engineering"},{"id":"8784","name":"electrical energy"},{"id":"178425","name":"Monolithic Power Systems"},{"id":"178426","name":"IEEE Transactions on Industrial Electronics"},{"id":"178427","name":"IEEE Industrial Electronics Society Conference"}],"core_research_areas":[{"id":"39531","name":"Energy and Sustainable Infrastructure"}],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EJackie Nemeth\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESchool of Electrical and Computer Engineering\u003C\/p\u003E\r\n\r\n\u003Cp\u003E404-894-2906\u003C\/p\u003E\r\n","format":"limited_html"}],"email":["jackie.nemeth@ece.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
