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"], "permalink_uri": "https://repo.qst.go.jp/records/76349", "pubdate": {"attribute_name": "公開日", "attribute_value": "2019-07-24"}, "publish_date": "2019-07-24", "publish_status": "0", "recid": "76349", "relation": {}, "relation_version_is_last": true, "title": ["Digital Control System Of High Precision Magnet Power Supply For SPring-8-Ⅱ"], "weko_shared_id": -1}
