Since the Single Turn Coil Domain computes the loop potential, this voltage induced across the coil can be used to compute the mutual inductance
which is given as follows:
The free-space inductance
L (in nanohenries) of a width of U-patch is d and I length, (in microns) given by [10,11].
When a metal particle passes radially above the spiral planar coil, peak inductance
change appears in the metal particle located at the axis of the coil in a spherical coordinate system (R, 0,0) as shown in Figure 2.
Figure 8 shows the calculated mutual inductance
in thick line and its derivative in thin line.
It has a rated Current between 0.45~1.60A, an inductance
value between 10 and 100mH and a DCR between 285 and 2,920mΩ.
5 for the inductance
value of 0.82 mH which is empirically measured for proposed high frequency full bridge converter transformer.
These sensors operate by using built-in electronics to measure the resonant frequency of an oscillator circuit with an inductive probe whose inductance
is varied by the position of the conductive gun-drilled rod over it.
Thus, when a vehicle passes over a loop, we can obtain what is commonly known as "the vehicle magnetic profile" or "the vehicle inductance
signature" by analyzing the inductance
or frequency variation recorded.
That's because the flyback transformer needs to have a primary inductance
value of 530 pH to keep peak currents under 2.3 A, so as not to overstress the external 650 V MOSFET.
The formulas for PCB inductance
and capacitance are complicated: the ones given in Figure 2 and 3 are approximations.
of meander line can be calculated from the following expressions
