Abstract
It is used for drive circuit magnetic core the invention discloses one kind, the magnetic core includes 4 side legs（1）、（2）、（3）、（4）, 1 cylindrical center pillar（5）.The magnetic core is formed by Ferrite Material sintering, or is formed by metal soft magnetic powder compacting.
Description
Technical field
It is used for drive circuit magnetic core the present invention relates to a kind of magnetic core, more particularly to one kind.
Background technology
LED illumination drive circuit needs to use a kind of complex-shaped magnetic core, conventional magnetic core magnetic core is occurred leakage inductance in use due to some defects in design, so as to considerably increase product power consumption, reduce illumination efficiency.In order to solve this problem, by optimizing design to core const ruction, so that magnetic core disclosure satisfy that design requirement.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art, there is provided one kind can be applied to LED illumination drive circuit, and the magnetic core that can be manufactured by high-volume low cost.
The technical solution adopted in the present invention is：One kind is used for drive circuit magnetic core, and the magnetic core includes 4 side legs（1）、（2）、（3）、（4）, 1 cylindrical center pillar（5）.The magnetic core is formed by Ferrite Material sintering, or is formed by metal soft magnetic powder compacting.
The beneficial effects of the invention are as follows：Design is optimized to core const ruction, magnetic core is reduced leakage inductance in use, so as to greatly reduce product power consumption, improve LED illumination efficiency.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is single magnetic core stereogram.
Specific embodiment
The technical solution adopted in the present invention is：One kind is used for drive circuit magnetic core, and the magnetic core includes 4 side legs（1）、（2）、（3）、（4）, 1 cylindrical center pillar（5）.The magnetic core is formed by Ferrite Material sintering, or is formed by metal soft magnetic powder compacting.
