3500/15-05-05-00电源模块是一种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。一般来说,这类模块称为负载 (POL) 电源供应系统或使用点电源供应系统 (PUPS)。


3500/15-05-05-00电源模块按变换方式一般分为AC转DC或DC转DC,可以将交流电和直流电进行相互转换。一个完整的电源模块一般由输入整流滤波器、单片开关电源、高频变压器、漏级钳位保护电路、光耦反馈电路、输出整流滤波器、偏置电路等部分组成。


由于电源模块具有小体积、高集成度、高性价比和最佳性能指标等特点,只需要最简的外围电路,配上少量分立式元件即可使用。当产品设计需更改时,只需并联或替换电源模块即可。


由于电源模块的这些优点,它被广泛应用于许多领域,如交换设备、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、航空航天等。尤其近几年由于数据业务的飞速发展和分布式供电系统的不断推广,模块电源的增幅已经超出了一次电源。

3500/15-05-05-00 A power supply module is a power supply that can be mounted directly on a printed circuit board and features power for application-specific integrated circuits (ASics), digital signal processors (DSPS), microprocessors, memory, field programmable gate arrays (FPgas), and other digital or analog loads. In general, such modules are called load (POL) power supply systems or point-of-use power supply systems (PUPS).


3500/15-05-05-00 The power module is generally divided into AC to DC or DC to DC according to the conversion mode, which can convert alternating current and direct current to each other. A complete power module is generally composed of input rectifier filter, single-chip switching power supply, high-frequency transformer, leakage clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts.


Because the power module has the characteristics of small size, high integration, high cost performance and the best performance index, only the simplest peripheral circuit is required, and a small number of discrete components can be used. When the product design needs to be changed, just parallel or replace the power module.


Due to these advantages of the power module, it is widely used in many fields, such as switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers and other communication fields and automotive electronics, aerospace and so on. Especially in recent years, due to the rapid development of data services and the continuous promotion of distributed power supply systems, the increase of module power supplies has exceeded the primary power supply.
