General design guidelines found in the literature point to an increase in mutual inductance by making the coils similar in shape, positioning them as close as possible, and using high-permeability soft-cores to concentrate the flux between them. But these recommendations are often difficult to follow in dynamic inductive wireless power transfer (DIWPT) configurations for vehicular applications. This is mostly due to the necessity of a mechanical clearance between the lane and the vehicle assembly, which creates an \u201cair gap\u201d. Also, unless tracks are used, the lateral movement of a vehicle over a primary coil potentially causes a variation in the induced voltage, which is not adequate to energize the powertrain. Considering these intrinsic problems of DIWPT applications, we developed a few theorems that might facilitate some optimum designs, in the case where rectangular secondary coils are used over oblong primary coils, for two different design targets: (i) maximum induced voltage on the secondary coil and (ii) better insensitivity to the vehicle lateral misalignment on the inductive lane.<\/jats:p>","DOI":"10.3390\/app15052313","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T06:39:07Z","timestamp":1740119947000},"page":"2313","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimum Geometries for Wireless Power Transfer Between an Oblong Coil and a Rectangular Coil"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3892-0369","authenticated-orcid":false,"given":"Luiz Alberto","family":"Lisboa Cardoso","sequence":"first","affiliation":[{"name":"ALGORITMI Research Centre, Intelligent Systems Associate Laboratory (LASI), University of Minho, 4800-058 Guimar\u00e3es, Portugal"},{"name":"Department of Electronics Technology, University of Vigo, 36310 Vigo, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9195-1239","authenticated-orcid":false,"given":"Jo\u00e3o L.","family":"Afonso","sequence":"additional","affiliation":[{"name":"ALGORITMI Research Centre, Intelligent Systems Associate Laboratory (LASI), University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8898-8903","authenticated-orcid":false,"given":"Andr\u00e9s","family":"Nogueiras Mel\u00e9ndez","sequence":"additional","affiliation":[{"name":"Department of Electronics Technology, University of Vigo, 36310 Vigo, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,21]]},"reference":[{"key":"ref_1","unstructured":"Hutin, M., and Leblanc, M.
