A blocking oscillator with a mesa type Si power transistor, is used as the switching unit. The off-time in the switching sequence is controlled by the error signal, which is obtained by comparing the output voltage to a reference voltage. Since the on-time is kept constant the duty ratio of the switching wave form varies and the filtered output of the switched voltage is regulated to a fixed value (+12V). The repetition frequency of the switching oscillator changes between 5 kc/s and 10 kc/s corresponding to the input voltage variation between 15V and 25V. The overall efficiency of this circuit is about 90%, and the contributions of each components or units to the power loss are estimated as follows: a) Loss in the switching element: 3% b) Loss in the smoothing filter: 1.2% c) Loss in the error detecting circuit: 2.0% d) Loss in the off-time control transistor: 3.8% Several modifications of high efficiency Switching mode voltage regulator are also suggested.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124960000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空研究所宇宙工学"},{"subitem_text_value":"東京大学宇宙航空研究所宇宙工学"},{"subitem_text_value":"東京大学宇宙航空研究所宇宙工学"},{"subitem_text_value":"東京大学宇宙航空研究所宇宙工学"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"野村, 民也"}],"nameIdentifiers":[{"nameIdentifier":"406636","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"林, 友直"}],"nameIdentifiers":[{"nameIdentifier":"406637","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"長江, 幸昭"}],"nameIdentifiers":[{"nameIdentifier":"406638","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福滝, 隆"}],"nameIdentifiers":[{"nameIdentifier":"406639","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NOMURA, Tamiya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"406640","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HAYASHI, Tomonao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"406641","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NAGAE, Sachiaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"406642","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"FUKUTAKI, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"406643","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0124960.pdf","filesize":[{"value":"385.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124960.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31899/files/SA0124960.pdf"},"version_id":"f7234047-14ca-4655-9381-e774f785b1ed"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"人工衛星用高能率安定化電源","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"人工衛星用高能率安定化電源"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31899","relation_version_is_last":true,"title":["人工衛星用高能率安定化電源"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:47:10.663407+00:00"}
