china electrical transformer mainly by the high-frequency transformer core (core) and two or more coils, they do not change position, from one or more of the electrical circuit, through the AC power through electromagnetic induction, Into AC voltage and current. In the electronic circuit plays a boost, buck, isolation, rectification, frequency, phase, impedance matching, inverter, energy storage, filtering and so on. 2. Electronic transformer works - constitute

A simple conventional type transformer consists of a closed magnet and two windings. One of the windings is connected to the AC source and is called the primary winding Np. The other winding can be connected to the load, called the secondary winding Ns. If the primary winding is connected to the power supply of the AC voltage Ui, the transformer is in no-load and the alternating current Io is generated in the primary winding, and Io is called the no-load current.
