It can provide power supply for the field programmable microprocessor (FPGA), ASIC (analog circuit board) and other special-purpose signal modules, which can be directly pasted on the field programmable microprocessor (FPGA) or FPGA. Generally speaking, such modules are called load (POL) power supply system or point of use power supply system (pups). Due to the advantages of modular structure, modular power supply is widely used in switching equipment, access equipment, mobile communication, microwave communication, optical transmission, router and other communication fields, 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 system, the increase of module power supply has exceeded that of primary power supply. The module power supply has isolation function, strong anti-interference ability, self-contained protection function and easy integration. With the extensive use of semiconductor technology, packaging technology and high-frequency soft switches, the power density of module power supply is increasing, the conversion efficiency is higher and higher, and the application is simpler and simpler.
Power module
In the field of switching power supply technology, people develop relevant power electronic devices while developing switching frequency conversion technology. The two promote each other and promote the development of switching power supply towards light, small, thin, low noise, high reliability and anti-interference at a growth rate of more than two digits every year. Switching power supply can be divided into AC / DC and DC / DC. DC / DC converter has realized modularization, and the design technology and production process have been mature and standardized at home and abroad, and have been recognized by users. However, due to its own characteristics, AC / DC modularization encounters more complex technical and process manufacturing problems in the process of modularization. The following describes the structure and characteristics of the two types of switching power supplies
