Transformers for Switching Power

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…
