Abstract :
In this paper, high efficiency full bridge LLC resonant converter for server power system is introduced. LLC resonant converter was reported in many papers recently because of its simple structure, high efficiency and high switching frequency ability. However, many SMPS designers and field engineers still encounter technical difficulties of power stage design and control scheme due to environmental regulations of power system. This paper clearly presents theoretical and practical details involved with the dynamic analysis and design procedures. The accuracy of dynamic analysis and validity of optimal design are confirmed with both computer simulations and experimental measurement.
