What does a high-voltage input module power supply look like?(5)

reasonable core structure and compact structure.
At the same time, in order to reduce the size of the module switching power supply, the switching frequency of the module switching power supply should be increased as much as possible. If it is to be increased to about 500kHz or higher, the loss of the ordinary magnetic core material is very large, and the magnetic core is easily overheated and magnetically saturated, and even It cannot work normally, so the high-frequency magnetic core material with excellent magnetic properties must be selected in the module switching power supply.

Regardless of how much control the product material and production process are, aging needs to be checked. Because the incoming inspection of electronic components and transformers is difficult to control, the quality stability of this batch of power supplies and whether the materials are detected to have potential safety hazards can only be detected through aging and high-temperature sampling of the entire batch of power supplies.
