High frequency transformer is as the most important part of Switching Power Supply.Transformer be conversion alternating voltage, electric current and
The device of impedance, when being connected with alternating current in primary coil, exchange flux is just produced in magnetic core, make to induce in secondary coil
Voltage or electric current.Transformer is made up of magnetic core and coil, and coil has two or more windings, wherein connecing the winding of power supply
Primary coil is, remaining winding is secondary coil.
The factor for selecting to consider during core structure has, and reduces leakage field and leakage inductance, increases coil area of dissipation, is advantageous to shield
Cover, coil-winding is easy, assembling easy-to-connect etc..Leakage field and leakage inductance have direct relation, magnetic core parameter with core structure
In design, to pay special attention to operating magnetic field flux density and be more than being limited by magnetization curve, also to be limited by being lost, while and and work(
The working method of rate transmission is relevant.
Ferrite is that one kind has ferromagnetic metal oxide.For electrical characteristics, ferritic resistivity ratio metal,
Alloy magnetic material is much bigger, and also has higher dielectric properties.Have when ferritic magnetic property is also manifested by high frequency compared with
High magnetic conductivity.Thus, ferrite has turned into the widely used nonmetal magnetic material in high frequency light current field.
At present, high frequency transformer uses U-typed magnetic core more with FERRITE CORE, but the length of air gap is unadjustable, with
Temperature rise, the change of air gap diminishes greatly can be uncontrollable because concrete reason changes, and is unfavorable for the long-term work of magnetic core.
Utility model content
In order to overcome the shortcomings of the prior art, the utility model, which provides one kind, can automatically adjust air gap, regulation
Radiating, improve the novel high-frequency transformer FERRITE CORE of transformer safety.
