In order to provide many power supplies with a reasonably low cost in a short production period, we developed a common current control system using a digital feedback control technology. The system consists of a high-precision analog-digital converter (ADC) circuit and a feedback controller using a field programmable gate array (FPGA). We tested a DC power supply equipped with the above digital feedback control system, and confirmed that the current ripple could be suppressed to less than 5 ppm  (pk-pk).   We also prototyped a high power DC power supply with 650 A based on a modularization concept. We also prototyped a DC-link power supply for a steering magnet with synchronized current output between 3 ports.\n\n","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"10th International Particle Accelerator Conference","subitem_description_type":"Other"}]},"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":"Kondo, Chikara"}],"nameIdentifiers":[{"nameIdentifier":"771130","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishimori, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"771131","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Hitoshi"}],"nameIdentifiers":[{"nameIdentifier":"771132","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukami, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"771133","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saji, Choji"}],"nameIdentifiers":[{"nameIdentifier":"771134","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Takahiro"}],"nameIdentifiers":[{"nameIdentifier":"771135","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takano, Shiro"}],"nameIdentifiers":[{"nameIdentifier":"771136","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukui, Toru"}],"nameIdentifiers":[{"nameIdentifier":"771137","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakazawa, Shingo"}],"nameIdentifiers":[{"nameIdentifier":"771138","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kondo, Chikara","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"771139","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishimori, Nobuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"771140","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"771141","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukami, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"771142","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saji, Choji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"771143","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"771144","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takano, Shiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"771145","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Digital Control System Of High Precision Magnet Power Supply For SPring-8-Ⅱ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Digital Control System Of High Precision Magnet Power Supply For SPring-8-Ⅱ"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-24"},"publish_date":"2019-07-24","publish_status":"0","recid":"76349","relation_version_is_last":true,"title":["Digital Control System Of High Precision Magnet Power Supply For SPring-8-Ⅱ"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:27:43.292054+00:00"}
