To overcome these challenges, a novel higher voltage step\u2010down ICPT topology is proposed by incorporating the hybrid switched capacitor (HSC) inverter and synchronous inverse coupled current doubler rectifier (SICCDR). Thus, the distinctive features of the proposed IPT system are as follows: (1) the voltage across four primary switches is reduced to half of the input voltage because of the special switched capacitor structure; (2) the reduced designing difficulties for the compensation parameters and loosely coupled transformer due to the inherent one\u2010eighth voltage step\u2010down ratio; and (3) the decreased secondary conduction loss contributed by SICCDR. To verify the claimed features of the proposed solution, a 500\u2010W IPT prototype with 400\u2010V input and 12\u2010V output is built and tested. The experimental results show that the efficiency achieves 91.3% in full load condition and peaks at 96.1%.<\/jats:p>","DOI":"10.1002\/cta.70075","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T00:09:57Z","timestamp":1753229397000},"page":"1329-1342","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A
