However, the different CEPs usually have different power and frequency requirements to ensure various transmission characteristics. In order to meet the transmission requirements of CEPs with different power and frequency needs, this paper proposes a novel dual\u2010frequency power allocation method for OWPT. This method achieves independent regulation of output power for loads of different frequencies through the designed SS topology dual\u2010frequency resonant compensation structure and establishes corresponding parameter design methods. A dual\u2010frequency OWPT platform operating at 40\u2009kHz\/100\u2009kHz was built to verify the correctness and effectiveness of the power allocation method. Experimental results show that when the input voltage corresponding to only one frequency changes, only the output power of the load corresponding to that frequency changes accordingly. Meanwhile, under the condition of dual\u2010load power supply, when the receiving coil is within a 90\u00b0 offset range, the system's output power ranges from 49.25 to 57.15\u2009W with a fluctuation rate of 14.8%, and the output efficiency ranges from 76.67% to 78.68% with a fluctuation rate of 2.59%.<\/jats:p>","DOI":"10.1002\/cta.4569","type":"journal-article","created":{"date-parts":[[2025,5,12]],"date-time":"2025-05-12T03:01:13Z","timestamp":1747018873000},"page":"110-122","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Dual\u2010Frequency
