高度集成的低姿態AC/DC轉換器模塊是即插即用前端解決方案。

　　隨著分布式電源架構的增殖（DPA）和中間總線架構（IBA）在數據中心的服務器和電信設備，系統設計人員正在部署完整的交流/直流轉換器內置功率因數校正（PFC）和輸入/輸出濾波滿足國家和國際監管能源標準。這些轉換器也被設計成提供一個超低配置文件，滿足嚴格的空間要求和非常高的轉換效率，以盡量減少功率損失的緊湊型封裝更多的權力。

　　在這些集成AC / DC模塊中包含的其他顯著特征包括：通用輸入、熱插拔能力、n + 1冗余的主動負載共享、內置智能和操作靈活性。板接口如我2C、PMBus和以太網包括使實時監控和基于負載水平或其他系統參數的動態數字控制。

　　In essence， these integrated and efficient universal input AC/DC front-end modules are being deployed as complete sub-systems to power a variety of DC/DC converters spread across the system. And while this laundry list of required features and benefits might be expected to frighten off some suppliers， there are in fact a number of manufacturers competing in this arena. Among the companies delivering plug-and-play AC front-end solutions for these applications are names like CUI， Artesyn Embedded Technologies （the former Emerson Embedded Computing & Power business of Emerson Network Power）， GE Energy， TDK-Lambda， and Vicor Corp.

　　This article will describe some recently introduced plug-and-play type AC/DC front-ends and highlight key features tailored for applications such as ITE， telecom and datacom systems， and industrial usage.
