The negative voltage converter, an improved version of the full bridge rectifier coupled with an active diode implementation is used to convert the extracted AC power from the transducer. The simulation results shows that the power extraction efficiency of the proposed rectifier is 2.2 times that of a conventional full bridge rectifier and more than 82% of power conversion can be achieve. To complete the harvesting system a low powered DC-DC Buck converter is used to regulate the power extracted by the rectifier to run a wireless sensor node operating at 1.5V voltage and 2mA current. The buck converter has a load regulation measured at 0.18mV/mA, and a line regulation of 0.18mV/V. The buck converter has a maximum efficiency of 84% with 1% voltage ripple. The die size for the overall layout is 1008um X 1008um including pads.\r The negative voltage converter with active diode architecture has been proposed. It has been shown that it can extract equal or superior output power while maintaining circuit simplicity compared to other existing works. The project was considered successful since the proposed design achieved and met the specified requirements to be able to run the load application chosen. This is specifically proposed to obtain an appreciable efficiency so as not to waste the scavenge energy. Additionally, smaller overall layout area was achieved. The efficiency of the converter is measured at 84%, even though there is no rule of thumb, but every design aims the highest result."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Energy Harvesting"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "A Piezoelectric energy harvesting interface circuit using negative voltage converter with active Diode and DC-DC buck converter.pdf", "filesize": [{"value": "753 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 753000.0, "url": {"url": "https://meral.edu.mm/record/2690/files/A Piezoelectric energy harvesting interface circuit using negative voltage converter with active Diode and DC-DC buck converter.pdf"}, "version_id": "109a903c-deee-447c-ac61-3f0f374936b9"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "8th AUN/SEED-Net Regional Conference on Electrical and Electronics Engineering"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Lowaton, Alieno C."}, {"subitem_authors_fullname": "Jilluh, Qadier I."}, {"subitem_authors_fullname": "Vergara, Thesa L."}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2015"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://uyr.uy.edu.mm/handle/123456789/461"}, "item_title": "A Piezoelectric Energy Harvesting Interface Circuit Using Negative Voltage Converter with Active Diode and DC-DC Buck Converter", "item_type_id": "21", "owner": "1", "path": ["1582967549708"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000002690", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "2690", "relation": {}, "relation_version_is_last": true, "title": ["A Piezoelectric Energy Harvesting Interface Circuit Using Negative Voltage Converter with Active Diode and DC-DC Buck Converter"], "weko_shared_id": -1}
