Transformers for Switching Power Supplies

In the daily contact with electronic products, we can find that there are a large number of magnetic core components, including the heart of the switching power supply - switching transformer.

Now the electronic products in life, the appearance of the product is increasinglysmall, ultra-thin requirements, and as the high-frequency switching power supply of the energy source heart of these electronic products, it has the advantages of high efficiency, good temperature and small size.

Transformer is a device that uses the principle of electromagnetic induction to exchange current, and its main components include primary coil, secondary coil and iron core.

The relationship between the number of coil turns and the output voltage:

In simple terms, the voltage ratio of the primary and secondary coils is equal to the turns ratio of the primary and secondary coils, so if you want to output different voltages, changing the turns ratio of the coils can be achieved.

The coil material of the transformer is enameled wire, three-layer insulated wire, copper foil, copper sheet.

Enameled wire generally uses multiple strands of stranded wire, the advantage of multiple strands of stranded wire is to avoid the skin effect of copper wire, but multiple strands of stranded wire may cause noise. Three-layer insulated wire is used in transformers with insufficient safety distance or small skeleton area, and copper foil and copper sheet are used in high-power transformers.

Our main products are Electronic Transformer、I-type Inductor、Common Mode Inductor and so on.

Please contact us if necessary. Look forward to your sincere cooperation.
