中文摘要

随着数据中心能耗增加,负载点变换器或电压调节模块需具备高效率与高功率密度以满足服务器大电流需求。本文针对48V总线电压降压需求,提出了一种用于多相LLC变换器的五中心变压器设计,旨在优化高电流输出场景下的功率转换效率与密度。

English Abstract

The role of data centers has become significant in the era of information technology, and their operation consumes a substantial amount of energy. Therefore, the point-of-load converter or voltage regulation module used in data centers must have high efficiency and power density to deliver a large current to specific servers. A common bus voltage 48 V at the rack stage needs to be stepped down to ...
