It is launched with the ASTRO-H in February 2016 as a piggyback on an H-IIA rocket. The main mission of HORYU-IV is to acquire on-orbit data of discharge phenomena occurring on high-voltage solar arrays. An electrical power subsystem (EPS) is one of the HORYU-IV bus subsystems. The function of the EPS is to provide uninterrupted power to all subsystems during the satellite’s lifetime. High reliability, high efficiency and simplicity are the main requirements to be considered in the design of an EPS. Generally, an EPS consists of solar arrays, rechargeable batteries, and a power control and distribution unit (PCDU). A peak power tracking topology is preferred to extract the maximum power generated by the solar arrays. The extra energy is stored in nickel-metal hydride batteries. The simple design and usage of available commercial-off-the-shelf components are the main features of the PCDU which controls the battery charging and load voltage regulation. Functional tests under different operating conditions were carried out on the designed EPS to qualify its performance. The aim of this research is to develop EPS with the “Lean” concepts and methods to achieve low cost and fast delivery subsystem. All design details have been explained and the test results have been analyzed. The in-orbit data have been analyzed to verify the design.","subitem_description_type":"Abstract"}]},"item_20_description_5":{"attribute_name":"備考","attribute_value_mlt":[{"subitem_description":"九州工業大学博士学位論文 学位記番号:工博甲第426号 学位授与年月日:平成28年9月23日","subitem_description_type":"Other"}]},"item_20_description_60":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_description":"平成28年度","subitem_description_type":"Other"}]},"item_20_dissertation_number_62":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第426号"}]},"item_20_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"33920","nameIdentifierScheme":"WEKO"}],"names":[{"name":"イドリス,  モハメッド ヤヒア"}]}]},"item_20_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18997/00004744","subitem_identifier_reg_type":"JaLC"}]},"item_20_text_34":{"attribute_name":"アドバイザー","attribute_value_mlt":[{"subitem_text_value":"趙, 孟佑"}]},"item_20_version_type_63":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Edries, Mohamed Yahia","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-12-27"}],"displaytype":"detail","filename":"kou_k_426.pdf","filesize":[{"value":"17.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kou_k_426.pdf","objectType":"fulltext","url":"https://kyutech.repo.nii.ac.jp/record/4750/files/kou_k_426.pdf"},"version_id":"9f330860-f0f8-4691-a6c1-55fd2b1bb1ec"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Lean Satellite","subitem_subject_scheme":"Other"},{"subitem_subject":"Electrical Power Subsystem","subitem_subject_scheme":"Other"},{"subitem_subject":"HORYU-IV","subitem_subject_scheme":"Other"},{"subitem_subject":"Peak Power Tracking","subitem_subject_scheme":"Other"},{"subitem_subject":"Nickel-Metal-Hydride Batteries","subitem_subject_scheme":"Other"},{"subitem_subject":"Solar Arrays","subitem_subject_scheme":"Other"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Design and Testing of a Lean Satellite Electrical Power Subsystem, HORYU-IV","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Design and Testing of a Lean Satellite Electrical Power Subsystem, HORYU-IV","subitem_title_language":"en"}]},"item_type_id":"20","owner":"18","path":["7"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-12-27"},"publish_date":"2016-12-27","publish_status":"0","recid":"4750","relation_version_is_last":true,"title":["Design and Testing of a Lean Satellite Electrical Power Subsystem, HORYU-IV"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-08-05T09:06:40.558669+00:00"}
