The magnetic circuit explanation of the double inductance of the non-coupled formula of the utility model：
The double inductance device constructed as above of the non-coupled formula of the utility model and the special magnetic circuit in assembling instruction, formed
Structure can realize the non-coupled technique effect of double inductance, illustrate with reference to the magnetic flux schematic diagram and 6 magnetic circuit of corresponding diagram of such as Fig. 5
The analysis of figure：First, when sheet metal coil 5 works, magnetic flux path theoretically can be as shown in Figure 5.Assuming that magnetic circuit is total
Magnetomotive force F=N*I (F：Magnetomotive force, N：The number of turn, I：Excitation current), equivalent magnetic circuit is as shown in Figure 6.Due to the magnetic in iron-core workpiece
Core magnetic conductivity is far longer than the magnetic conductivity of air, thus magnetic resistance R2, R3, R5 and R7 with air gap portion be far longer than it is other
Magnetic resistance R1, R4 and R6.However magnetic flux always circulates as electric current in the magnetic circuit of low magnetic resistance, the access magnetic flux of high magnetic resistance
It can be less.By analysis it is seen that magnetic resistance R5, R6 and R7 series connection after with R4 be parallel to magnetomotive force F=N*I driving it is equivalent
In magnetic circuit, therefore the magnetic flux of magnetic resistance R5, R6, R7 bypass is almost nil, that is, when sheet metal coil 5 has the magnetic flux of excitation magnetic potential
It is during gesture F=N*I, then very low in the degree of coupling of sheet metal coil 4.
For the leakage magnetic flux of inductance, in such inductance with air gap, certain leakage field can be generated in air gap periphery
Logical 30, leakage magnetic flux 30 be also cause couple between double inductance one can not irrespective factor with towards.The utility model is non-
Relative position is apart from distant between air gap designed by the double inductance devices of manifold type, compared to general existing non-I-shaped sections
The design that core is combined with left and right c-type iron core, then the utility model is utmostly to avoid between double inductance that leakage magnetic flux is brought
Coupling, effectively realize the ultralow coefficient of coup.
In addition need the person of emphasizing, in the structure design of the double inductance devices of the above-mentioned non-coupled formula of the utility model, the first inductance with
The inductance value of second inductance is to control the air gap of inductance by the thickness of different right side plates 7 and left side plates 6 respectively
So as to obtain required inductance value.Two inductance values can be it is identical, can not also be same, can by right side plates 7 with it is left
The thickness of side plates 6 is controlled by.The DC resistance for further relating to the first inductance and the second inductance is respectively by right side
Sheet metal coil 5 and the structure of left side sheet metal coil 4 determined, the DC resistances of two inductance can be it is identical,
Can be different.In addition, the device of the double inductance of the non-coupled formula of the utility model, can pass through above-mentioned conductive pin 42,52
The lower surface 16 of main iron core body 1 is extended beyond, so as to fulfill by the high effect of the device body frame of the double inductance of non-coupled formula,
So that other components or device can also be placed on the bottom of the double inductance of non-coupled formula further to save printed circuit board (PCB)
Using space, and improve power density.
