摘　　要：针对绿色节能型、环境友好型数据中心进行低压配电设备设计,提出基于电压纹波注入技术的双反星型变压整流器,用于数据中心低压大电流工作场合,通过纹波注入电路从平衡电抗器(Interphase Reactor,IPR)二次侧绕组提取纹波电压能量注入到负载侧,实现废弃能量的再次利用,达到12脉波输出特性。详细论证变压整流器工作原理,各个区间工作模态,并进行实验研究证明理论分析的正确性。Aiming at the design of low-voltage distribution equipment in green,energy-saving and environment-friendly data center,a double-reverse star transformer rectifier based on voltage ripple injection technology is proposed,which is used in low-voltage and high-current working places of data center.Ripple voltage energy is extracted from interphase reactor(IPR),secondary winding by ripple injection circuit and injected into load side,thus realizing the reuse of waste energy and achieving 12-pulse output characteristics.The working principle and working modes of each section of the transformer rectifier are demonstrated in detail,and experimental research proves the correctness of the theoretical analysis.
