用于服务器和数据中心的12V或48V输入、0.9V输出有源钳位正激变换器功率模块

DC-to-DC power supplies are critical components for processors in high performance computing and datacenter servers. Conversion from an intermediate bus voltage (e.g., 12 or 48 V) to the core voltage (∼0.9 V) of processors must be efficient, compact, and cost effective. This paper proposes two versions of active-clamp forward converter (ACFC) power blocks to supply core voltage from either 12 or 4...
