本論文針對冷備援式伺服器電源系統進行研究,提出數位冷備援式控制策略,藉由數位訊號處理器TMS320F28035來實現冷備援式控制機制。所實現的冷備援式電源供應器,能夠達到低待機損耗、高效率、可模組並聯的需求。當系統重載時使用雙台模組,輕載時使用單台模組,極輕載時進入突衝模式改善輕載效率。本論文採用雙台數位控制半橋串聯諧振轉換器做為直流/直流轉換模組主要架構,輸出規格為12 V/ 54 A。並考慮此架構在輕載或空載時輸出電壓穩定及改善效率,而加入突衝模式策略。數位控制電路包含均流控制電路、Oring MOSFET控制與輸出電壓回授控制。文中並針對冷備援式系統數位控制、半橋串聯諧振轉換器及並聯均流技術與Oring MOSFET控制做原理說明與設計考量。
This thesis aims to study cold-redundancy technology for server power supply system. The redundant power supply meets the needs of high efficiency and high reliability for parallel modules. The cold-redundancy technology can reduce the standby power consumption of a server power. The cold redundant power supply system is operated at normal mode under medium and heavy load conditions. Two modules provide all the load power in parallel. When the load drops to 45% of the rated load, one module is shut down and only single module provides all the load power to raise the efficiency performance. In this thesis, two digital controlled half-bridge series resonant converters module are adopted as the main circuit topologies. The output specifications of the prototype system are 12V/54A. Under light-load/ no-load conditions, a burst mode control is used to regulate the output voltage and achieve high efficiency. The control circuit includes protection circuit, automatic master-slave current-sharing and hot-swap function with an Oring MOSFET control. The operating principles and design considerations are also analyzed and discussed.
