GE模块IC646PHA772

电源模块是可以直接贴装在印刷电路板上的电源供应器，其特点是可为专用集成电路(ASIC)、数字信号处理器 (DSP)、微处

理器、存储器、现场可编程门阵列 

(FPGA) 

及其他数字或模拟负载提供供电。电源模块广泛用于交换设备、接入设备、移动通讯、微波通讯以及光传输、路由器等通信领

域和汽车电子、那么电源模块的作用是什么？

一、隔离

1、安全隔离：强电弱电隔离\IGBT隔离驱动\浪涌隔离保护\雷电隔离保护(如人体接触的电子设备的隔离保护)

2、噪声隔离：(模拟电路与数字电路隔离、强弱信号隔离)

3、接地环路消除：远程信号传输\分布式电源供电系统。

二、保护

短路保护、过压保护、欠压保护、过流保护、其它保护。

三、电压变换

升压变换\降压变换\交直流转换(AC/DC、DC/AC)\极变换(正负极转换、单电源与正负电源转换、单电源与多电源转换)。

四、稳压

交流市电供电远程直流供电\分布式电源供电系统电池供电。
