The magnetic core comprises a semi-elliptical side leg (1), a rectangular middle column (2), an elliptical middle column (3), a rectangular side leg (4) and a bottom plate (5). The magnetic core is made of a sintered ferrite material and is pressed by metal soft magnetic powder.

Description

technical field [0001] The invention relates to a magnetic core, in particular to a DEC magnetic core for LED choke coils. Background technique [0002] The LED lighting drive circuit needs to use a magnetic core with a complex shape. Due to some defects in the design of the previous magnetic core, the magnetic core has leakage inductance during use, which greatly increases the power consumption of the product and reduces the lighting efficiency. In order to solve this problem, the magnetic core can meet the design requirements by optimizing the design of the magnetic core structure. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a magnetic core that can be applied to LED lighting driving circuits and can be manufactured in large quantities at low cost. [0004] The technical solution adopted in the present invention is: a DEC magnetic core for LED choke coils, th...
