Abstract :
In the developed trend of high efficiency and high density power , LLC resonant converter has become a research focus. This paper analyzes the working principle of LLC resonant circuit and synchronous rectification scheme with secondary current Self-driven type and to design and verify the circuit based on the chip UCC25600. The results show that the LLC resonant converter has advantages of high converting efficiency and simple structure, etc, and it can be more suitable for the requirements of high frequency switching and high efficiency.
