1669 2020 2020 eng conferenceobject IEEE 1 -- 2020-11-29 -- A transformer with variable primary windings for wide input voltage range DC/DC converters is presented. This transformer structure allows three states of the primary winding to be converted by only two individual windings. Based on the evaluations of a two-switch flyback converter, the potential of DC/DC converters with variable structures, the implementation of such a transformer and the advantages and disadvantages are shown and discussed. Real measurement results demonstrate the noticeable increase in efficiency and the reduction in component stress, having a positive influence on the operation of the converter and the component selection during the design process. 2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia) 10.1109/ipemc-ecceasia48364.2020.9367869 true {"status":"ok","message-type":"work","message-version":"1.0.0","message":{"indexed":{"date-parts":[[2024,3,1]],"date-time":"2024-03-01T17:12:28Z","timestamp":1709313148209},"reference-count":21,"publisher":"IEEE","license":[{"start":{"date-parts":[[2020,11,29]],"date-time":"2020-11-29T00:00:00Z","timestamp":1606608000000},"content-version":"vor","delay-in-days":0,"URL":"https:\/\/ieeexplore.ieee.org\/Xplorehelp\/downloads\/license-information\/IEEE.html"},{"start":{"date-parts":[[2020,11,29]],"date-time":"2020-11-29T00:00:00Z","timestamp":1606608000000},"content-version":"stm-asf","delay-in-days":0,"URL":"https:\/\/doi.org\/10.15223\/policy-029"},{"start":{"date-parts":[[2020,11,29]],"date-time":"2020-11-29T00:00:00Z","timestamp":1606608000000},"content-version":"stm-asf","delay-in-days":0,"URL":"https:\/\/doi.org\/10.15223\/policy-037"}],"funder":[{"DOI":"10.13039\/501100004725","name":"Ministry of Economic Affairs","doi-asserted-by":"publisher"}],"content-domain":{"domain":[],"crossmark-restriction":false},"short-container-title":[],"published-print":{"date-parts":[[2020,11,29]]},"DOI":"10.1109\/ipemc-ecceasia48364.2020.9367869","type":"proceedings-article","created":{"date-parts":[[2021,3,9]],"date-time":"2021-03-09T22:23:26Z","timestamp":1615328606000},"source":"Crossref","is-referenced-by-count":1,"title":["Reconfigurable Transformer for Wide Input Voltage Range DC\/DC Converters"],"prefix":"10.1109","author":[{"given":"Michael","family":"Gerstner","sequence":"first","affiliation":[]},{"given":"Martin","family":"Maerz","sequence":"additional","affiliation":[]},{"given":"Armin","family":"Dietz","sequence":"additional","affiliation":[]}],"member":"263","reference":[{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1109\/INTLEC.1997.645896"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1109\/COMPEL.2017.8013350"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2018.2795959"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1109\/APEC.2016.7468221"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2016.2645891"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2017.2773484"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2018.2876346"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1109\/APEC.2018.8341219"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1109\/COMPEL.2017.8013350"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2018.2795959"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1109\/ICPE.2015.7168056"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1109\/IECON.2016.7793540"},{"key":"ref6","first-page":"668","article-title":"Low power multiple output dc supply -
