Abstract

The invention discloses a PV magnetic core for a choking coil. The magnetic core comprises three side legs (1), (2) and (3), a hexagonal center pillar (4) and a base plate (5). The magnetic core is formed by sintering a ferrite material or pressing metal soft magnetic powder.

Description

technical field [0001] The invention relates to a magnetic core, in particular to a PV magnetic core for a choke coil. Background technique [0002] The lighting drive circuit needs to use a magnetic core with 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 lighting driving circuits and can be manufactured in large quantities at low cost. [0004] The technical solution adopted in the present invention is: a PV magnetic core for choke coils, the magnetic core incl...
