Embodiment approach

[0017] Please refer to figure 1 and figure 2 , the magnetic bead modeling method of the present invention is used to model the magnetic beads, so that the magnetic beads can be applied correctly. A preferred embodiment of the magnetic bead modeling method of the present invention comprises the following steps:

[0018] Step S101 , define the components of the magnetic bead model 1 according to the function of the magnetic bead, including an inductor L, a capacitor C, a heat dissipation resistor Rs and a DC resistance Rdc. Since the inductance L will generate heat loss during transmission, the components of the magnetic bead model 1 also include a heat dissipation resistor Rs. Since each component has loss during the DC transmission process, the components of the magnetic bead model 1 also include a DC resistance Rdc.

[0019] Step S102, set up magnetic bead model 1 (see figure 2 ), in the magnetic bead model 1, the connection relationship between the inductance L, the ca...

Abstract

A method for building a magnetic bead mathematical model includes defining component elements of the model of the magnetic bead, building the model of the magnetic bead, obtaining a characteristic curve of an impedance of a magnetic bead in a standard magnetic bead specification of the magnetic bead, ascertaining parameters of the component elements, simulating the model of the magnetic bead, and comparing the characteristic curve with the characteristic curve in the standard magnetic bead specification, to further optimize the mode of the magnetic bead.

Description

technical field [0001] The invention relates to a magnetic bead modeling method. Background technique [0002] In circuit board design, magnetic beads are often equivalent to a series connection of an inductor and a resistor. However, according to the characteristics of the inductor, it can be known that the impedance of the inductor will increase with the increase of the frequency under high frequency conditions. According to the characteristics of the magnetic beads, it can be known that the impedance of the magnetic beads decreases with the increase of the frequency under high frequency conditions, so that the magnetic beads are equivalent to a series connection of an inductor and a resistor, and it is impossible to obtain a magnetic bead pair circuit under high frequency conditions. The evaluation and calculation of the effect, making it impossible to apply the magnetic beads correctly. Contents of the invention [0003] In view of the above, it is necessary to provi...
