The loss of high-power module switching power supply mainly includes four parts: high-frequency switching loss, high-frequency transformer loss, rectification loss and line conduction loss. In the application of low voltage and high current output, the rectification loss and line conduction loss account for a larger proportion. .

DC module power supply have many advantages and are widely used. Whether it is switching equipment or access equipment, whether it is mobile communication or microwave communication, whether it is optical transmission or router,DC module power supply it can play its role. It is very common in this field. What does a suitable power module look like? How to choose?

One: circuit design principles and techniques

DC module power supply The distinction between good circuit principles and bad circuit principles can often only be made from a professional perspective. At this stage, power modules can be roughly divided into two types: bare board and potting. The bare board can be based on intuitive methods, such as the layout of electronic components is reasonable, neat, generous, neat, and the solder joints are bright and straight. For encapsulated modules, it is not possible to see the internal conditions, but since the internal conditions are not exposed, it is much better in terms of safety and performance metrics. The soldering process can include hand soldering and wave soldering. The quality of the wave soldering process of mechanized production is better than that of manual soldering.
