...Dangshu Wang; Pengpeng Xie; Menghu Chang; Zelong Hou; Nongke Li; Guangzhen Wu; Xinxia Wang Purpose Aiming at the core issue of traditional LLC resonant converters losing zero-voltage switching ( ZVS ) conditions under wide input voltage range, leading to drastic efficiency degradation...

...Dangshu Wang; Menghu Chang; Licong Zhao; Yuxuan Yang; Zhimin Guan Purpose This study aims to regarding the application of traditional pulse frequency modulation control full-bridge LLC resonant converters in wide output voltage fields such as on-board chargers, there are issues with wide frequency...

...Xuliang Yao; Xiao Han; Yuefeng Liao; Jingfang Wang Purpose This study aims to solve the problem that under light-load conditions, the output voltage regulation capability is lost due to the fact that the voltage gain of the LLC resonant converter does not decrease with the increase...

...Xuliang Yao; Xiao Han; Yuefeng Liao; Jingfang Wang Purpose This paper aims to better design the resonant tank parameters for LLC resonant converter. And, it is found that under heavy load, the voltage gain is affected by junction capacitors of the primary side switching and the parasitic...
