LLC变换器的数字控制思想，基于C语言的算法。-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
