Description
Technical field
The utility model relates to a kind of resonant inductances.
Background technique
Traditional resonant inductance is made of FERRITE CORE (PQ type, EE type magnetic core etc.) and Ritz line winding group.Ferrite magnetic
Core μ value is very high to be needed to increase very big air gap when doing resonant inductance, generallys use distributed air gap.There is leakage field generation at air gap
The excessively high inductance performance of inductor wire packet temperature rise is caused to be deteriorated.And it is influenced by air gap leakage field, line packet need to be isolated at air gap, cannot be close
It is adjacent to magnetic core, the dosage of litz wire, which increases, when coiling line packet consumes more costs.
Utility model content
In view of the deficiencies of the prior art, the utility model is intended to provide a kind of resonant inductance, and center pillar magnetic core is metal powder magnetic
Core, bottom plate and corner are FERRITE CORE, and stem metal-powder-core magnetic core μ value is low to be not necessarily to when doing resonant inductance increase air gap, inductance
Magnetic leakage free generates, and line packet does not have the excessively high problem of temperature, improves overall performance.
The utility model is achieved through the following technical solutions.
A kind of resonant inductance, the first magnetic core and the second magnetic core being oppositely arranged including two, first magnetic core and second
Core structure is identical, and first magnetic core includes that center pillar magnetic core, the protrusion of bottom plate, protrusion in the middle part of bottom plate are set to bottom plate or so
The corner of two sides, the bottom plate and corner are FERRITE CORE, and the center pillar magnetic core is metal powder magnetic core, the center pillar magnetic core
It is equipped with winding.
Preferably, the bottom plate and corner are an integral structure.
Preferably, the winding is Ritz line winding group.
Preferably, the center pillar magnetic core of the center pillar magnetic core of first magnetic core and the second magnetic core is bonded air-gap-free.
Preferably, the either flush of the center pillar magnetic core and the corner.
Preferably, the center pillar magnetic core is cylinder.
Compared with prior art, the utility model has the advantages that: the first magnetic core and the second magnetic core are by FERRITE CORE and gold
Belong to the mixing of powder magnetic core to constitute, center pillar magnetic core is metal powder magnetic core, and bottom plate and corner are FERRITE CORE, stem metal-powder-core magnetic core
μ value is low without increasing air gap when doing resonant inductance, and inductance magnetic leakage free generates, and line packet does not have the excessively high problem of temperature, improves whole
Performance；Winding is Ritz line winding group, and line packet can closely be adjacent to magnetic core when coiling, and the dosage of litz wire is reduced, reduce inductance at
This.
