In order to improve the misalignment tolerance of the system, this article proposes a high misalignment tolerance WPT system with constant current output based on the asymmetric arc\u2010shaped coupler and LCC\u2010P compensation topology. This design effectively increases the horizontal and rotation misalignment tolerance, so that the fluctuation of the overall efficiency and power of the system greatly declines when coming across disturbances. The article firstly establishes the equivalent circuit model and deduces the equations about parameter configuration and the output characteristics of the system. Furthermore, the asymmetric arc\u2010shaped coupler is designed, and the mutual inductance fluctuation of the coupler is verified to be within 8.7% through simulation. Finally, a 500\u2010W\u2010level experimental prototype based on the WPT design is built and tested to verify the performance and effectiveness. The prototype achieves stable performance with an output power about 580\u2009W and an 85% overall efficiency when the horizontal misalignment distance varies from 0 to 40\u2009mm and the misalignment angle varies from 0 to 35\u00b0.<\/jats:p>","DOI":"10.1002\/cta.4493","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T23:38:38Z","timestamp":1741736318000},"page":"6228-6242","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["An Asymmetric Arc\u2010Shaped Coupler\u2013Based WPT Design for High Misalignment Tolerance Charging of AUVs"],"prefix":"10.1002","volume":"53","author":[{"given":"Shuming","family":"Deng","sequence":"first","affiliation":[{"name":"Hubei Key Laboratory of Power Equipment &amp; System Security for Integrated Energy, School of Electrical Engineering and Automation Wuhan University  Wuhan Hubei China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9139-6287","authenticated-orcid":false,"given":"Changsong","family":"Cai","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Power Equipment &amp; System Security for Integrated Energy, School of Electrical Engineering and Automation Wuhan University  Wuhan Hubei China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6032-3352","authenticated-orcid":false,"given":"Junhua","family":"Wang","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Power Equipment &amp; System Security for Integrated Energy, School of Electrical Engineering and Automation Wuhan University  Wuhan Hubei China"}]},{"given":"Yufeng","family":"Jiang","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Power Equipment &amp; System Security for Integrated Energy, School of Electrical Engineering and Automation Wuhan University  Wuhan Hubei China"}]},{"given":"Xian","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Reliability and Intelligence of Electrical Equipment Hebei University of Technology  Tianjin China"}]},{"given":"Leke","family":"Wan","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Power Equipment &amp; System Security for Integrated Energy, School of Electrical Engineering and Automation Wuhan University  Wuhan Hubei China"}]},{"given":"Xi","family":"Wu","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Power Equipment &amp; System Security for Integrated Energy, School of Electrical Engineering and Automation Wuhan University  Wuhan Hubei China"}]},{"given":"Yinfeng","family":"Du","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Power Equipment &amp; System Security for Integrated Energy, School of Electrical Engineering and Automation Wuhan University  Wuhan Hubei China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8732-3624","authenticated-orcid":false,"given":"Yingguo","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering Jiangsu University of Science and Technology  Zhenjiang China"}]}],"member":"311","published-online":{"date-parts":[[2025,2,25]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"crossref","unstructured":"I.Belkin J.
