When the nonlinear inductance is excited by the current of a certain frequency, the subharmonic of half the frequency oscillates in the tank circuit composed of the nonlinear inductance and a capacitance. Such two second-subharmonic parametric oscillators are excited by currents with a phase difference of 180 degrees, respectively. The voltages with a phase difference of 90 degrees oscillate in the tank circuit of two parametric oscillators. Thus single-phase AC power is converted into two-phase AC power. Furthermore, it is converted into three-phase AC power by Scott's connection. Single-phase AC power of frequency f is converted into two-phase or three-phase AC power of frequency f/2 by using only inductance and capacitance. The experimental results of the conversion of single-phase AC of frequency 60 c/s into two-phase AC and three-phase AC are treated. The nonlinear inductance makes use of an iron core. The conversion characteristics of two-phase and three-phase AC versus input single-phase AC and DC bias current show that the operation of the converter is very good. The conversion efficiency is nearly 90 % in favorable conditions. When the converter is excited by the current of the single-phase full rectified wave, the phase converter having no frequency change is obtained. But this efficiency is nearly 20 %. In this paper, the polyphase rectifier using the converter is described as an application. These results show that the phase converter may be useful.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 16: 11-30 (1963)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"丹野,  頼元","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Engineering16-02.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering16-02.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13110/files/Engineering16-02.pdf"},"version_id":"029c3e95-5b79-48b7-8d11-477c24700db7"}]},"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":"パラメータ励振現象による単相多相電力変換装置とそれを利用した整流電源装置について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"パラメータ励振現象による単相多相電力変換装置とそれを利用した整流電源装置について","subitem_title_language":"ja"},{"subitem_title":"Phase Conversion which Utilizes Parametric Oscillation and Polyphase Rectifier Using It.","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1291"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-03"},"publish_date":"2009-03-03","publish_status":"0","recid":"13110","relation_version_is_last":true,"title":["パラメータ励振現象による単相多相電力変換装置とそれを利用した整流電源装置について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T04:46:59.320197+00:00"}
