按现代电力电子的应用领域，我们把

电源模块划分如下：

绿色电源模块

高

速发展的计算机技术带领人类进入了

信息社会,同时也了电源模块技术

的迅速发展。八十年代,计算机采

用了开关电源,完成计算机电源换

代。接着开关电源技术相继进入了电

子、电器设备领域。

计算机技术的发

展,提出绿色电脑和绿色电源模块。绿

色电脑泛指对环境无害的个人电脑和

相关产品，绿色电源系指与绿色电脑

相关的省电电源,根据美国环境保

护署1992年6月17日“能源之星"计划

规定,桌上型个人电脑或相关的外围设

备,在睡眠状态下的耗电量若小于30瓦

,就符合绿色电脑的要求,提高电源效

率是降低电源消耗的根本途径。就目 

前效率为75%的200瓦开关电源而言,电

源自身要消耗50瓦的能源。

开关电源

模块

通信业的迅速发展的推动了

通信电源的发展。高频小型化的开关

电源及其技术已成为现代通信供电系

统的主流。在通信领域中,通常将整流

器称为一次电源,而将直流-直流

(DC/DC)变换器称为二次电源。一次电

源的作用是将单相或三相交流电网变

换成标称值为48V的直流电源。当前在

程控交换机用的一次电源中,传统的相

控式稳压电源己被高频开关电源取代,

高频开关电源(也称为开关型整流器

SMR)通过MOSFET或IGBT的高频工作,开

关频率一般控制在50-100kHz范围内,

实现率和小型化。近几年,开关整

流器的功率容量不断扩大,单机容量己

从48V/12.5A、48V/20A扩大到

48V/200A、48V/400A。

开关电源(4张)

因通信设备中所用集成电路的种类繁

多,其电源电压也各不相同,在通信供

电系统中采用高功率密度的高频DC-DC

隔离电源模块,从中间母线电压(一般

为48V直流)变换成所需的各种直流电

压,这样可大大减小损耗、方便维护,

且安装、增加非常方便。一般都可直

接装在标准控制板上,对二次电源的要

求是高功率密度。因通信容量的不断

增加,通信电源容量也将不断增加。
