the principle of Transformer

Farady transformer   is converting AC voltage, current and impedance of the device, when the primary coil through AC current, core (or cores) and then generates an alternating magnetic flux, so that the secondary coil induces a voltage (or current). The transformer core (or cores) and coil, the coil has two or more windings, wherein the power supply is called the primary coil winding, the secondary winding is called the rest of the winding. In the generator, either the coil moves through the magnetic field or magnetic field moves through the stationary coil, can EMF in the coil, in both cases, the value of the magnetic flux are the same, but there is the number of the magnetic flux intersecting the coil chain change, which is the principle of mutual induction. Transformer is a kind of mutual use of electromagnetic induction, the transformation of voltage, current and impedance of the device. Press the Power Phase Classification: single-phase transformer, three-phase transformer, multi-phase transformer.
