摘　　要：高性能计算已经迈入后E量级时代,对于高性能处理器的供电技术提出了大功率、低电压、快响应的严苛要求。但是,目前的国产数字多相控制器和DrMOS功率器件无法满足低电压条件下大功率的供电需求。为解决该问题,通过数字多相控制器的1个相位驱动2个DrMOS,提出每相位“1推2”的工程设计方案,实现供电能力加倍。通过器件选型、参数设置、反馈均流等技术手段,控制纹波噪声、动态响应以及多相均流,确保该方案满足工程规范要求。详细介绍了该方案的原理和实现方法,同时搭建验证系统对该方案的可行性和有效性进行了验证。High-performance computing has entered the post-exascale computing era,which poses stringent requirements for power supply technology for high-performance processors,including high power,low voltage,and fast response.However,current domestic digital multi-phase controllers and DrMOS power devices cannot meet the power supply requirements for high power at low voltage.To address this issue,a"1 drive 2"engineering design solution is proposed,which utilizes one phase of the digital multi-phase controller to drive two DrMOS per phase,thereby effectively doubling the power delivery capability.By using device selection,parameter setting,and feedback equalization techniques,the scheme controls ripple noise,dynamic response,and multi-phase equalization to ensure that the scheme meets engineering specification requirements.This paper details the principle and implementation of the scheme,and builds a verification system to verify the feasibility and effectiveness of the scheme.
