【 摘 要 】

The efficiency improvement of switching converters has always been a research hotspot. This paper analyzes the loss of LLC resonant converter including magnetic components loss and Switching loss. For easier analysis, a mathematical model of the switching tube is established, and then derive the formula of the loss. The synchronous rectification technology is used to improve the efficiency of the LLC, and finally established a simulation model to verify the correctness of the technology to improve the efficiency of the converter.
