A Flat Wire Vertical Winding High Current Power Inductor

Abstract

The invention discloses a flat wire vertical winding type large-current power inductor. The flat wire vertical winding type large-current power inductor comprises a magnetic core, wherein a coil is wound on the magnetic core. The flat wire vertical winding type large-current power inductor also comprises a skeleton, wherein the skeleton comprises an upper skeleton and a lower skeleton; the magnetic core comprises an upper magnetic core and a lower magnetic core; the upper magnetic core is detachably connected onto the upper skeleton; the lower magnetic core is detachably connected onto the lower skeleton; the upper skeleton is spliced to the lower skeleton; and the coil is formed by winding a flat wire. The flat wire vertical winding type large-current power inductor has the advantages that modular design is adopted and the cost is reduced.

Description

【Technical field】 [0001] The invention relates to a flat wire vertical winding type large current power inductor. 【Background technique】 [0002] At present, under the limited size, the large current value that the round wire inductor cannot meet. And the development direction of the SMT inductor is to reduce the volume, reduce the cost, miniaturize and thin. Commonly used ordinary inductors are high in height and poor in heat dissipation. At the same time, the traditional winding process results in low transformer efficiency and large losses. Therefore, the existing SMT inductors also use flat wires to form flat coils. Compared with round wires, they have better air ducts, better heat dissipation, high efficiency, and low cost, but there are also problems. The coils wound by flat wires are relatively fixed. Different inductances use coils with different inner diameters. For this reason, enterprises often have to redesign the entire magnetic core during manufacturing, and t...

[0002] At present, under the limited size, the large current value that the round wire inductor cannot meet. And the development direction of the SMT inductor is to reduce the volume, reduce the cost, miniaturize and thin

Commonly used ordinary inductors are high in height and poor in heat dissipation. At the same time, the traditional winding process results in low transformer efficiency and large losses.

Therefore, the existing SMT inductors also use flat wires to form flat coils. Compared with round wires, they have better air ducts, better heat dissipation, high efficiency, and low cost, but there are also problems. The coils wound by flat wires are relatively fixed. Different inductances use coils with different inner diameters. For this reason, companies often have to redesign the entire magnetic core during production and manufacturing, and the cost is high.
