The switching power supply module modularizes the discrete components on the switching power supply to form a smaller, higher power module power supply. Its internal circuit is also a switching power supply.

 

Switching power supply can be divided into two major categories: AC/DC and DC/DC. The DC/DC converter has been modularized, and the design technology and production process have been matured and standardized at home and abroad, and have been recognized by users, but The modularity of AC/DC, due to its own characteristics, leads to more complex technical and process manufacturing problems in the process of modularization.
