Description
Technical field
It is vertical around inductance coil and vertical around inductance that the present invention relates to inductance component technical fields more particularly to a kind of flat wire
Device.
Background technology
Using flat wire it is vertical around power inductor, in recent years in photovoltaic DC-to-AC converter, UPS, DC charging stubs
Etc. being widely used in various high-frequency high-power Switching Power Supplies.Standing around coiling for flat conductor, is exactly that conductor width is remote
It is rectangular flat conductor more than the cross sectional shape of conductor thickness, as shown in Figure 1, the normal direction of the width of conducting wire, along
The thickness side of conducting wire carries out bending side around realizing the purpose of more the number of turns coiling in specific coil entire length.
With the needs that the high efficiency, high power density, Highgrade integration of above-mentioned various high-frequency high-power power supplys develop, electricity
The bulk of source entirety is extremely compressed, and inside the circuit of these power supply products, essential power magnetic cell
For size in occupation of the most significant dimensional space of power volume, the reduction of the size of these power inductance components becomes power supply
Therefore how one of most important design object of product in the case where keeping identical electricity function index, further subtracts
The volume of small vertical winding type power inductance, the power attenuation for reducing inductance and then the vertical cost around power inductance is further decreased, is
Where the purpose of the present invention.
The tops Fig. 2 are common rectangular vertical around inductance coil, it is vertical around into line by the spring flat wire of several circles
The thickness of the lateral total length L of circle, flat wire is t, and the width of flat wire is w, and wherein width w is several times of flat wire thickness t
To tens times.It is molded around coiling to be stood along diagram direction the flat wire of width-thickness ratio w/t, needs will have certain fillet
The vertical winding fixture around coil winding machine on the inside of flat wire, by flat wire along inside bending and molding.Due to make flat line side
To being bent, flat wire madial wall will bear huge folding stress at this time, and the thickness t of flat wire is relatively thin, unit area institute
The folding stress born is very big, and the result of bending so that as shown under Fig. 2, the flat wire on the inside of bent angle is crushed to form R
Angle pit, copper wire inner thickness, which is extruded, at this time thickens, according to the size of flat wire width-thickness ratio, the more flat wire of big flakiness ratio,
The ratio between its inner thickness and thickness t before flat wire bending d/t are more much larger than 1, simultaneously as the bending on the outside of flat wire bending
Stroke averagely turns round stroke much larger than flat wire, as a result causes the outside flat wire at bending angle to be stretched thinning, here it is it is vertical around
There is the reason of gap is big on the outside of coil, and inside thickens in flat wire coil afterwards.It is flat at 3 times or more for commonly using width-thickness ratio w/t
Horizontal line, especially after the bending of the small angles R, d>>T so that minimum overall length L=n × d of coil>>N × t (n is coil turn), this
The smaller radius bend of sample, i.e., the smaller angles bending R are stood around inductance coil, and the minimum length L that the coil of identical the number of turns is total becomes
It is longer so that the length dimension of inductance cannot be controlled effectively.
