本論文旨在研製一應用於機櫃式伺服器電腦中央處理器之電壓調節模組,此模組可將電源供應器的12 V轉換成中央處理器所需要的工作電壓1.6 V~2.0 V,並以數位控制晶片實現電壓、電流偵測與系統穩定度控制設計,且能符合英特爾中央處理器規範。電壓調節模組電路使用「多相式降壓型同步整流轉換器」作為電路主結構,並搭載六相各交錯60 º導通的功率級實現電源設計。電路工作原理、設計考量以及系統穩定度控制等皆於本論文中進行詳細分析與探討。論文中藉由模擬與實際測試各項電氣驗證,證明能符合Intel CPU的設計規範。電源轉換器最大輸出電流255 A,轉換效率最高達95 %,且可提供快速暫態響應以及可靠的系統穩定度控制等特色。
This thesis aims to study and develop a voltage regulator module (VRM) for central processor unit (CPU) in rack server system. This module transfers 12V from power supply units to 1.6V~2.0V output that CPU needs; design uses digital integrated circuit control chip to realize voltage, current monitor, system stability control, and meets Intel CPU spec. The VRM circuit consists of multi-phase synchronous buck converter and six-phase power stages which interleave each other by 60º. The circuit operation theory, design consideration and system stability control will be analyzed and discussed in the thesis. Design is verified meeting Intel CPU specification by simulation and real electrical validation. This module is capable of supporting maximum output current 255A, maximum conversion efficiency 95%, and also providing fast transient reposes and reliable system stability control features.
