The invention provides a power inductor and a manufacturing method thereof. The power inductor includes two first magnetic cores each having a perpendicularly connected center pillar portion and a cover portion, a second magnetic core having a perpendicularly connected long plate portion and two support portions, and a coil having a winding portion surrounded by an insulated wire and two conductive portions extending from both ends of the insulated wire. Two first magnetic cores are joined to each other in abutment with respective center pillar portions, the coil winding portion sleeves the center pillar portions of the two first magnetic cores abutting against each other, and the second magnetic core is provided with two support portions on the cover portions of the two first magnetic cores and is separated from the two first magnetic cores. The power inductor of the present invention forms a closed magnetic circuit by a combination of the two first magnetic cores, the second magneticcore and the coil, and has ideal inductance and current resistance.
Description
technical field [0001] The invention relates to a power inductor, in particular to a high-power energy storage inductor and a manufacturing method thereof. Background technique [0002] Generally, high-power inductors used in power supply on the market, such as power supply for charging devices, air conditioners, or home appliances, are often required for active power factor correction (Power Factor Correction; PFC) design because of their high power and labor-intensive nature. . [0003] Ring products can meet the requirements of low frequency, high current, and low core loss required for high-power inductor design. Such as figure 1 As shown, the toroidal inductor 1 includes a toroidal core 11 and a coil 12 wound on the toroidal core 11 . [0004] However, toroidal inductors need to manually wind the wires on the toroidal core 11 to form the coil 12, and the wires are easy to be damaged during the winding process of the coil 12, resulting in unstable product characterist...
