EE4215 High-Frequency Transformer Manufacturer Customized DW3649
Transformer Features
high frequency transformer has the characteristics of small size, cheap price,Large transmission power, low loss, wide frequency range ,low temperature rise,stable performance and so on.
Transformer is to transform ac voltage, current and impedance of the device, when the primary zhongtong have alternating current coil, iron core (or core) to produce ac magnetic flux, induced in the secondary coil voltage (or current). A transformer consists of an iron core (or a magnet) and a coil. The coil has two or more windings, of which the winding is called a primary coil and the rest is called a secondary coil.
Transformer Application
high frequency transformer is often used in mobile phone chargers, DC-DC converters, drive transformers, adapters, power supplies, etc.
Transformers are more efficient at higher frequencies.
They are widely applicable to personal electronics, electric car, energy conversion, and tec.
