DCF803-0035開關電源模塊

通信業的迅速發展極*的推動了通信電源的發展。高頻小型化的開關電源及其技術已成為現代通信供電系統的主流。在通信領域中,通常將整流器稱為一次電源,而將直流-直流(DC/DC)變換器稱為二次電源。一次電源的作用是將單相或三相交流電網變換成標稱值為48V的直流電源。

DCF803-0035當前在程控交換機用的一次電源中,傳統的相控式穩壓電源己被高頻開關電源取代,高頻開關電源(也稱為開關型整流器SMR)通過MOSFET或IGBT的高頻工作,開關頻率一般控制在50-100kHz范圍內,實現*效率和小型化。近幾年,開關整流器的功率容量不斷擴大,單機容量己從48V/12.5A、48V/20A擴大到48V/200A、48V/400A。

DCF803-0035因通信設備中所用集成電路的種類繁多,其電源電壓也各不相同,在通信供電系統中采用高功率密度的高頻DC-DC隔離電源模塊,從中間母線電壓(一般為48V直流)變換成所需的各種直流電壓,這樣可大大減小損耗、方便維護,且安裝、增加非常方便。一般都可直接裝在標準控制板上,對二次電源的要求是高功率密度。因通信容量的不斷增加,通信電源容量也將不斷增加。

DCF803-0035 Switching power supply module

DCF803-0035 The rapid development of the communication industry has greatly promoted the development of communication power supplies. High-frequency miniaturized switching power supply and its technology have become the mainstream of modern communication power supply systems. 

DCF803-0035 In the field of communications, the rectifier is usually called the primary power supply, and the DC-DC (DC/DC) converter is called the secondary power supply. The function of the primary power supply is to convert the single-phase or three-phase AC power grid into a DC power supply with a nominal value of 48V. Currently, in the primary power supply used in program-controlled switches, the traditional phase-controlled regulated power supply has been replaced by high-frequency switching power supply. The high-frequency switching power supply (also called switching rectifier SMR) works through the high frequency of MOSFET or IGBT. The switching frequency Generally controlled within the range of 50-100kHz to achieve high efficiency and miniaturization.

DCF803-0035 In recent years, the power capacity of switching rectifiers has continued to expand, and the single unit capacity has expanded from 48V/12.5A, 48V/20A to 48V/200A, 48V/400A.

DCF803-0035 Due to the wide variety of integrated circuits used in communication equipment, their power supply voltages are also different. In the communication power supply system, high-power density high-frequency DC-DC isolated power modules are used to convert the intermediate bus voltage (generally 48V DC) into Various DC voltages are required, which can greatly reduce losses, facilitate maintenance, and is very convenient to install and increase.

DCF803-0035 Generally, it can be installed directly on the standard control panel, and the requirement for the secondary power supply is high power density. As communication capacity continues to increase, communication power supply capacity will also continue to increase.
