Abstract:	本文提出可以平均分擔負載電流的交流/直流轉換器，此乃考量適合應用於大電流負載且擁有較佳擴充模組彈性需求的伺服器電腦系統。此電源供應器結構包含前端的電磁干擾濾波器，可有效消除電源供應器系統端雜訊所造成之干擾問題。前級使用主動零電壓功率因數修正器，後級使用全橋相移零電壓切換轉換器，皆運用零電壓切換技術以有效降低切換損失，進而提升全機效率。[1]控制電路包含保護電路及自動主僕式均流控制電路。文中並針對主動零電壓功率因數修正器、全橋相移零電壓轉換器及並聯均流技術的電路架構作原理說明。最後設計實作出二部1 kW 並聯均流伺服器電源供應器，其輸出電壓為24 V，輸出電流為40 A，效率約為82 %以上(在110 V 交流輸入)，分流率為±3 %以內。 This paper proposes an AC/DC converter with a load-current sharing feature. The studied converter is suitable for server power supplies demanding high output currents and flexible modulization. An EMI filter for suppressing the conducted noise resulting from the developed power supply is included at the front end, which is followed by a zero-voltage-switching (ZVS) active power factor corrector (PFC) and a ZVS phase-shift full-bridge DC/DC converter. The ZVS technique successfully reduces the switching losses and thus increases the overall efficiency. The main control system consists of several protection circuits and an automatic master-slave current-sharing controller. The operating principles for the ZVS PFC, the phase-shift full-bridge converter, and the master-slave current-sharing control are discussed. Two 1-kW prototype circuits of server power supplies are implemented and parallel operation is tested. The output voltage is 24 V, the output current is 40 A, and the overall efficiency is about 82% at 110V AC mains voltage. The error percentage of the current-sharing is less than ±3 % of the rated output current.
