Power supply modules are widely used in communication fields such as switching equipment, access equipment, mobile communication, routers, automotive electronics, aerospace, etc.
Due to the characteristics of short design period, high reliability and easy system upgrade, the application of power supply module is more and more extensive.
Especially in recent years, due to the rapid development of data services and the continuous promotion of distributed power supply systems, the growth rate of power supply modules has exceeded that of primary power supply.
With the extensive use of semiconductor technology, packaging technology and high-frequency soft switches, the power density of power supply modules is getting larger and larger, the conversion efficiency is getting higher and higher, and the application is becoming more and more simple. How to define the isolation of power supply module?
The isolation of power supply modules is generally divided into two types: one is. Isolation between input and output; That is, the input and output are not common ground;
The other is the isolation between output and output; Multiple sets of outputs are isolated from each other and do not interfere with each other.
