These programs do not have the same resources of traditional space programs; thus, low cost and fast delivery have been encouraged known as lean satellite programs. The delivery time of most of the small satellites is still more than two years and the failure rate of the small spacecraft is still a concern. Small satellites have the highest infant mortality rate and the Electrical Power System （EPS） is one the subsystems that contribute the most to the failure of CubeSats. To achieve fast delivery and low cost without compromise the reliability it is necessary to redefine the systems engineering of small spacecraft. Improvement in the development of EPS will contribute significantly to achieve the goals of low-cost and fast delivery of small spacecraft. The methods and guidelines for rapid development of electrical power systems have been proposed in this thesis. The architecture of EPS has been analyzed to diminish the failure rate that is related to the small spacecraft. In addition, a modular approach has been proposed to achieve rapid development and reliable systems. The module integrates the solar cells and the power condition units. Then, the EPS is designed integrating the required number of modules as it is demonstrated in Ten-Koh satellite.","subitem_description_language":"en","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484号 学位授与年月日：令和元年9月20日","subitem_description_type":"Other"}]},"item_20_description_60":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_description":"令和元年度","subitem_description_type":"Other"}]},"item_20_dissertation_number_62":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第484号"}]},"item_20_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18997/00007681","subitem_identifier_reg_type":"JaLC"}]},"item_20_select_64":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_20_text_34":{"attribute_name":"アドバイザー","attribute_value_mlt":[{"subitem_text_value":"奥山, 圭一"}]},"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":"Gonzalez Llorente,  Jesus David","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":"2020-03-31"}],"displaytype":"detail","filename":"kou_k_484.pdf","filesize":[{"value":"9.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kou_k_484.pdf","objectType":"fulltext","url":"https://kyutech.repo.nii.ac.jp/record/6471/files/kou_k_484.pdf"},"version_id":"47eb2cd4-313e-4dac-ad03-665c06284fff"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Small satellite","subitem_subject_scheme":"Other"},{"subitem_subject":"Micro-Satellite","subitem_subject_scheme":"Other"},{"subitem_subject":"Power Systems","subitem_subject_scheme":"Other"},{"subitem_subject":"Modular design","subitem_subject_scheme":"Other"},{"subitem_subject":"Spacecraft testing","subitem_subject_scheme":"Other"},{"subitem_subject":"Lean Satellite","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":"Study on Electrical Power System combining centralized and distributed architectures to promote rapid development and survival improvement in Small Spacecraft","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Study on Electrical Power System combining centralized and distributed architectures to promote rapid development and survival improvement in Small Spacecraft","subitem_title_language":"en"},{"subitem_title":"生存性向上と迅速な開発を実現できる集中型と分散型アーキテクチャを組み合わせた小型宇宙機電力システムに関する研究","subitem_title_language":"ja"}]},"item_type_id":"20","owner":"18","path":["7"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-03-31"},"publish_date":"2020-03-31","publish_status":"0","recid":"6471","relation_version_is_last":true,"title":["Study on Electrical Power System combining centralized and distributed architectures to promote rapid development and survival improvement in Small Spacecraft"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-01-16T02:50:28.086303+00:00"}
