The proposed analytical formulation accounts for the influence of the output current harmonic distortion on the conduction losses as well as the impact of the output parasitic capacitances and the deadtime on the switching losses. The losses are formulated in balanced conditions to select suitable SiC MOFETs for the desired target efficiency. To validate the proposed methodology, a 3-phase inverter is designed to present full load efficiency in excess of 99% when built using SiC MOSFETs antiparalleled with SiC Schottky diodes selected for the specified full load efficiency. Experimental assessment of the designed inverter efficiency is compared with the expected values from the proposed analytical formulation and shown to match or exceed the predicted results for loads ranging from 40% to 100% of full load.<\/jats:p>","DOI":"10.3390\/en16020818","type":"journal-article","created":{"date-parts":[[2023,1,11]],"date-time":"2023-01-11T04:59:58Z","timestamp":1673413198000},"page":"818","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["A Novel Analytical Formulation of SiC-MOSFET Losses to Size High-Efficiency Three-Phase Inverters"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3073-916X","authenticated-orcid":false,"given":"Pedro","family":"Costa","sequence":"first","affiliation":[{"name":"INESC-ID, Energy Systems, Green Energy and Smart Converters Group, 1000-029 Lisbon, Portugal"},{"name":"Departamento de Engenharia Eletrot\u00e9cnica e de Computadores, University of Lisbon, T\u00e9cnico Lisboa, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3266-7881","authenticated-orcid":false,"given":"S\u00f3nia","family":"Pinto","sequence":"additional","affiliation":[{"name":"INESC-ID, Energy Systems, Green Energy and Smart Converters Group, 1000-029 Lisbon, Portugal"},{"name":"Departamento de Engenharia Eletrot\u00e9cnica e de Computadores, University of Lisbon, T\u00e9cnico Lisboa, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2164-0739","authenticated-orcid":false,"given":"Jos\u00e9 Fernando","family":"Silva","sequence":"additional","affiliation":[{"name":"INESC-ID, Energy Systems, Green Energy and Smart Converters Group, 1000-029 Lisbon, Portugal"},{"name":"Departamento de Engenharia Eletrot\u00e9cnica e de Computadores, University of Lisbon, T\u00e9cnico Lisboa, 1049-001 Lisboa, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"034003","DOI":"10.1088\/0268-1242\/31\/3\/034003","article-title":"Practical Applications of SiC-MOSFETs and Further Developments","volume":"31","author":"Furuhashi","year":"2016","journal-title":"Semicond.
