Abstract
A novel over-current protection method for LLC resonant converter has been proposed in this paper. This method is very attractive for its good current limit ability, especially under short circuit condition. Moreover, its current limit point range is easy to be optimized. Detailed theoretical analysis and optimization design considerations have been presented. An experimental prototype converter based on the proposed method was built up to verify the theoretical analysis
