高度集成的低姿態(tài)AC/DC轉(zhuǎn)換器模塊是即插即用前端解決方案。

　　隨著分布式電源架構(gòu)的增殖（DPA）和中間總線架構(gòu)（IBA）在數(shù)據(jù)中心的服務(wù)器和電信設(shè)備，系統(tǒng)設(shè)計(jì)人員正在部署完整的交流/直流轉(zhuǎn)換器內(nèi)置功率因數(shù)校正（PFC）和輸入/輸出濾波滿足國(guó)家和國(guó)際監(jiān)管能源標(biāo)準(zhǔn)。這些轉(zhuǎn)換器也被設(shè)計(jì)成提供一個(gè)超低配置文件，滿足嚴(yán)格的空間要求和非常高的轉(zhuǎn)換效率，以盡量減少功率損失的緊湊型封裝更多的權(quán)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(dòng)負(fù)載共享、內(nèi)置智能和操作靈活性。板接口如我2C、PMBus和以太網(wǎng)包括使實(shí)時(shí)監(jiān)控和基于負(fù)載水平或其他系統(tǒng)參數(shù)的動(dòng)態(tài)數(shù)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.
