A high frequency electrical transformer

A high frequency electrical transformer   Introduce： Electronic transformers are mainly composed of high-frequency transformer magnetic core (iron core) and two or more coils, they do not change position, from one or more electrical circuits, through the AC power with the help of electromagnetic induction, into AC voltage and current. In the electronic circuit plays the role of boost, buck, isolation, rectification, frequency conversion, phase reversal, impedance matching, inverter, energy storage, filtering and so on. Constitute： A simple transformer is composed of a closed magnetic conductor and two windings, one of which is connected to the AC power supply, called the primary winding Np, and the other can be connected to the load, called the secondary winding Ns. If the primary winding is connected to a power supply with AC voltage Ui, the transformer is at no-load, generating alternating power supply Io in the primary winding, Io is called no-load current.  …
