在未来的应用中，电压调节器模块（VRMs）从银盒的12v输出获取功率是不切实际的，因为电压总线太低而无法提供更多的功率。因此，48v总线的分布式电源系统（dps）将是未来高端pc更可行的解决方案。本文主要对48个候选VRM进行了调查和比较。构建了6个48 V VRM原型并进行了比较：有源钳位正向、不对称半桥、对称半桥、推挽、推挽正向和集成滤波器推挽正向拓扑。
In future applications, it will be impractical for voltage regulator modules (VRMs) to draw power from the 12 V output of the silver box because the voltage bus will be too low to deliver more power. Therefore, distributed power systems (DPSs) with buses of 48 V will be more feasible solutions for future high-end PCs. This paper focuses primarily on the investigation and comparison of 48 V VRM candidates. Six 48 V VRM prototypes are built and compared: the active clamp forward, asymmetrical half bridge, symmetrical half bridge, push-pull, push-pull forward and integrated-filter push-pull forward topologies.
