A detailed derivation of asymmetrical CMV source in energy transmission (ET) and dead time resonance (DR) is presented, and a common mode (CM) equivalent circuit model considering stray parameters of power devices and transformer for the high\u2010voltage power <jats:italic>LLC<\/jats:italic> converter is constructed. This study assesses the influence of asymmetric junction capacitances of power devices and stray capacitances of transformer on both the CMV source and the CM model. It also examines the impact of power level on the constituent elements of the CMV source. Additionally, a theory of asymmetric CMV source cancellation is deduced based on the nonideal power <jats:italic>LLC<\/jats:italic> converter, where asymmetric noise source and coupling pathway are taken into account, which helps mitigate it through matching circuit structure without extra components. Finally, a 30\u2009kHz 2\u2009\u00d7\u200950\u2009kW prototype is constructed and validated to reduce the CMV where the experiments show that the output CMV within high\u2010frequency band could be reduced by 12.15\u2009dB at rated operating conditions.<\/jats:p>","DOI":"10.1002\/cta.4217","type":"journal-article","created":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T05:26:32Z","timestamp":1723181192000},"page":"2109-2124","update-policy":"https:\/\/linproxy.fan.workers.dev:443\/https\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["An asymmetrical cancellation method for common mode voltage in full\u2010bridge <i>LLC<\/i> converter utilizing nonideal transformer"],"prefix":"10.1002","volume":"53","author":[{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0001-5857-5921","authenticated-orcid":false,"given":"Xinbo","family":"Liu","sequence":"first","affiliation":[{"name":"School of Electrical Engineering Beijing Jiaotong University  Beijing China"},{"name":"Key Lab. of Vehicular Multi\u2010Energy Drive Systems (Beijing Jiaotong Univ.)
