The sensor is the most sensitive and reliable sensor among current sensors used in room temperature. This sensor can measure a few milliampere DC current. It is therefore applied in various measurements, in particular battery monitoring system. It is used for small current measurement. In this paper the author carries out driving sensor frequency measurement method due to measure large DC current, and of it due to measure large current. The author examines this method by using magnetic circuit analysis, measurement effect of fluxgate current sensor and , generic circuit simulator(LTspice) and obtain magnetic nonlinearity data by experiment. From these research the author confirm that core\u2019s characteristic and electric circuit characteristic affect sensor driving frequency and at last validate availability of this method and therefore the author conclude the limit of core characteristic", "subitem_description_type": "Abstract"}]}, "item_7_select_21": {"attribute_name": "\u5b66\u4f4d", "attribute_value_mlt": [{"subitem_select_item": "master"}]}, "item_7_subject_13": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "548", "subitem_subject_scheme": "NDC"}]}, "item_7_text_24": {"attribute_name": "\u7814\u7a76\u79d1\u30fb\u5c02\u653b", "attribute_value_mlt": [{"subitem_text_value": "\u60c5\u5831\u7406\u5de5\u5b66\u7cfb\u7814\u7a76\u79d1\u96fb\u5b50\u60c5\u5831\u5b66\u5c02\u653b"}]}, "item_7_text_36": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Thesis"}]}, "item_7_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u60c5\u5831\u7406\u5de5\u5b66\u7cfb\u7814\u7a76\u79d1 \u96fb\u5b50\u60c5\u5831\u5b66\u5c02\u653b"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u5c0f\u5e61, \u5bdb"}], "nameIdentifiers": [{"nameIdentifier": "5648", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-05-31"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "obata.pdf", "filesize": [{"value": "7.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 7500000.0, "url": {"label": "obata.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/1835/files/obata.pdf"}, "version_id": "0753302f-042a-47c1-994d-ea0b821e8dee"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "\u30bb\u30f3\u30b5\u99c6\u52d5\u5468\u6ce2\u6570\u3092\u7528\u3044\u305f\u5927\u96fb\u6d41\u6e2c\u5b9a\u7528\u30d5\u30e9\u30c3\u30af\u30b9\u30b2\u30fc\u30c8\u30bb\u30f3\u30b5", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u30bb\u30f3\u30b5\u99c6\u52d5\u5468\u6ce2\u6570\u3092\u7528\u3044\u305f\u5927\u96fb\u6d41\u6e2c\u5b9a\u7528\u30d5\u30e9\u30c3\u30af\u30b9\u30b2\u30fc\u30c8\u30bb\u30f3\u30b5"}]}, "item_type_id": "7", "owner": "1", "path": ["9/233/234", "34/105/262"], "permalink_uri": "http://hdl.handle.net/2261/28040", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2011-08-08"}, "publish_date": "2011-08-08", "publish_status": "0", "recid": "1835", "relation": {}, "relation_version_is_last": true, "title": ["\u30bb\u30f3\u30b5\u99c6\u52d5\u5468\u6ce2\u6570\u3092\u7528\u3044\u305f\u5927\u96fb\u6d41\u6e2c\u5b9a\u7528\u30d5\u30e9\u30c3\u30af\u30b9\u30b2\u30fc\u30c8\u30bb\u30f3\u30b5"], "weko_shared_id": null}
