Each rectifier outputs -200 kV, and the total five rectifiers are connected in a series. The feasibility of both gas insulation and gas cooling for semiconductor devices was validated to achieve dc-1 MV output and 1-h continuous operation. We devised a novel structure of cylindrical dense alignment of the heatsinks with stud-type diodes, which enables both the mitigation of electric-field concentration on the heatsinks and the improvement of heat dissipation from diodes. The difference in the temperature rise for three different directions of the heatsink in an SF 6 gas atmosphere was also clarified. The heat flow was analyzed to quantify the cooling effect of SF 6 gas, taking into account the gas circulation by the external cooling system. Rectification operation and temperature rise were tested with an actual-scale rectifier including a step-up transformer. Additionally, dc-1.2 MV withstand voltage was tested for a fifth-stage actual-scale rectifier. The test results demonstrated the validity of the proposed design.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEEE"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1109/TIA.2021.3096775","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ieeexplore.ieee.org/document/9484737","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0093-9994","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Akeshi Takahashi"}],"nameIdentifiers":[{"nameIdentifier":"1020560","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suto, Tetsuya"}],"nameIdentifiers":[{"nameIdentifier":"1020561","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Toshiaki"}],"nameIdentifiers":[{"nameIdentifier":"1020562","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Kohei"}],"nameIdentifiers":[{"nameIdentifier":"1020563","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroyuki Fujita"}],"nameIdentifiers":[{"nameIdentifier":"1020564","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiranuma, Yuki"}],"nameIdentifiers":[{"nameIdentifier":"1020565","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoshi Ichimura"}],"nameIdentifiers":[{"nameIdentifier":"1020566","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kazuhiro, Watanabe"}],"nameIdentifiers":[{"nameIdentifier":"1020567","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mieko, Kashiwagi"}],"nameIdentifiers":[{"nameIdentifier":"1020568","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tetsuya, Maejima"}],"nameIdentifiers":[{"nameIdentifier":"1020569","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroyuki, Tobari"}],"nameIdentifiers":[{"nameIdentifier":"1020570","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kazuhiro, Watanabe","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1020571","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mieko, Kashiwagi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1020572","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tetsuya, Maejima","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1020573","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroyuki, Tobari","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1020574","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"1 MV Rectifier With SF6-Gas Insulation and Cooling for ITER Neutral Beam Injector System","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"1 MV Rectifier With SF6-Gas Insulation and Cooling for ITER Neutral Beam Injector System"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-11-17"},"publish_date":"2021-11-17","publish_status":"0","recid":"84562","relation_version_is_last":true,"title":["1 MV Rectifier With SF6-Gas Insulation and Cooling for ITER Neutral Beam Injector System"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:20:47.575233+00:00"}
