基于混合谐振变换器的8:1总线变换器，实现3.5 kW/in³功率密度与98.6%效率，适用于48V数据中心电源系统

A hybrid resonant converter with a 1:1 turn-ratio autotransformer and two 2:1 turn-ratio transformers is proposed to achieve an 8:1 bus converter for 48V data-center power systems. Compared with conventional resonant converters, the turns and losses of the transformer windings of the proposed hybrid resonant converter are reduced. A matrix transformer with PCB windings is proposed to integrate the...
