一种用于数据中心应用的开关电容与串联谐振混合MHz级直流变压器

In the front-end of two-stage voltage regulator modules in 48 V-based data centers, a dc transformer (DCX) is required to convert the 48 V bus to an intermediate voltage with a fixed buck ratio. In this article, we present a novel switched-capacitor and series-resonant hybrid DCX specifically for this application. The proposed DCX combines a 2:1 resonant switched-capacitor cell with a series-reson...
