Generally speaking, this class module called load point (POL) power supply system or using a power supply system (PUPS). Because of the advantages of modular structure very much, therefore module power is widely used in the exchange equipment, access devices, mobile communications, microwave communication and optical transmission, routers and other communications field and automobile electronics, aerospace and other. Especially in recent years due to the rapid development of data services and the further promotion of distributed power supply system, module power supply growth is more than a power supply. Along with the semiconductor technology, encapsulation technology and high frequency the wide use of soft switch, module power supply power density is more and more big, the conversion efficiency more and more high, application is also more and more simple.
People in the switch power technology is the development of related edge of power electronics device, the side development
Love pu electronic power supply module (4 zhang) switch frequency conversion technology, both to promote each other push switch power for more than a year two digital growth toward light, small, thin, low noise and high reliability, anti-interference direction. Switching power supply can be divided into the AC/DC and DC/DC two kinds big, DC/DC converter is now realize modular, and design technology and production process at home and abroad are mature and standardization, and has set up a file users receive the recognition, but the AC/DC modular, because of its own characteristics in the process of makes modular, meet more complex technology and process manufacturing. The following are two kinds of switch power supply structure and characteristics in this paper
