Abstract
The utility model discloses a complex ferrite magnetic core for a power inductor, which comprises a T type magnetic core assembly A and a T type magnetic core assembly B that which are adhered to form an I-shaped magnetic core. The complex ferrite magnetic core meets dual requirements on high frequency and large-current resistance.
Description
Technical field
The utility model relates to a kind of ferrite core, and particularly a kind of power inductance is used the complex ferrite magnetic core.
Background technology
At present, along with fast development of information technology, the requirement with magnetic core also develops towards the high DC stacked direction of Kuan Pin ﹑ to power inductance.Existing power inductance is with the general independent employing NiZn ferrite of magnetic core, and the ferritic frequency of utilization of NiZn is higher, but saturation flux density Bs is lower, and the dc superposition characteristic of the device of making is relatively poor.
Summary of the invention
The utility model technical problem to be solved provides a kind of power inductance and uses the complex ferrite magnetic core, has satisfied the double requirements of power inductance with the anti-big electric current of Gao Pin ﹑ of magnetic core.
The technical scheme that the utility model technical solution problem adopts is: a kind of power inductance is used the complex ferrite magnetic core, comprises T type magnetic core assembly A and T type magnetic core assembly B, and said magnetic core assembly A and magnetic core assembly B are bonded to " worker " font magnetic core.
As a kind of preferred, said magnetic core assembly A adopts the MnZn Ferrite Material, and said magnetic core assembly B adopts the NiZn Ferrite Material.
In the utility model, the combination of T type magnetic core assembly A and T type magnetic core assembly B can adopt the mode of epoxy resin or waterglass bonding to realize.
The characteristic of General N iZn Ferrite Material and MnZn Ferrite Material contrasts like following table:
| Material | The NiZn ferrite | The MnZn ferrite |
| Applying frequency (Hz) | >1M | <2M |
| μ i | 5～2500 | 800～15000 |
| Bs(mT) | 250～500 | 350～600 |
| Tc(℃) | 120～450 | 120～450 |
The beneficial effect of the utility model is: " worker " font magnetic core that the T type magnetic core A through a NiZn Ferrite Material and the T type magnetic core B of a MnZn Ferrite Material are combined into; On the one hand since the ferritic frequency of utilization of NiZn apparently higher than the MnZn ferrite, thereby improved the frequency of utilization of device; On the other hand because the ferritic Bs of MnZn (350～600mT) be higher than the ferritic Bs of NiZn (250～500mT), thus improved the DC stacked performance of device.Adopt the combination of NiZn Ferrite Material and MnZn Ferrite Material to use, learn from other's strong points to offset one's weaknesses, thereby satisfied the double requirements of power inductance with the anti-big electric current of Gao Pin ﹑ of magnetic core.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Below in conjunction with accompanying drawing the utility model is further specified.
