高度集成的低姿态AC/DC转换器模块是即插即用前端解决方案。
随着分布式电源架构的增殖（DPA）和中间总线架构（IBA）在数据中心的服务器和电信设备，系统设计人员正在部署完整的交流/直流转换器内置功率因数校正（PFC）和输入/输出滤波满足国家和国际监管能源标准。这些转换器也被设计成提供一个超低配置文件，满足严格的空间要求和非常高的转换效率，以尽量减少功率损失的紧凑型封装更多的权力。
在这些集成AC / DC模块中包含的其他显著特征包括：通用输入、热插拔能力、n + 1冗余的主动负载共享、内置智能和操作灵活性。板接口如我²C、PMBus和以太网包括使实时监控和基于负载水平或其他系统参数的动态数字控制。
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.
