开关电源模块
通信业的迅速发展极·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·效率和小型化。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。
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。
