Inductive coupling matrix of a multiconductor system for a winding-on-core prototype

Abstract
Broadband circuit models for electric machines are

effective means to understand, predict, and control the

phenomenon of conducted Electromagnetic Interference (EMI)

from immunity/susceptibility perspective. These models should

cover the capacitive and inductive coupling behavior of the

component along the frequency range of interest. Circuit models

used under generic SPICE simulation softwares are very helpful

for design-related and troubleshooting activities. In this paper

the inductive coupling for a winding on a laminated ferromagnetic

core prototype has been investigated and analyzed with

the aid of freely-available FEMM software... (More)
Broadband circuit models for electric machines are

effective means to understand, predict, and control the

phenomenon of conducted Electromagnetic Interference (EMI)

from immunity/susceptibility perspective. These models should

cover the capacitive and inductive coupling behavior of the

component along the frequency range of interest. Circuit models

used under generic SPICE simulation softwares are very helpful

for design-related and troubleshooting activities. In this paper

the inductive coupling for a winding on a laminated ferromagnetic

core prototype has been investigated and analyzed with

the aid of freely-available FEMM software package.

Inductive coupling analysis resulted in the generation of a

complex-numbered inductive coupling matrix expressing a

certain wiring arrangement. This is achieved by automatically

generating the desired geometry and assigning boundary

conditions for the problem under FEMM through Lua scripting

language and then solving for magneto-static and time-harmonic

magnetic cases for both self- and mutual- inductances for every

conductor in the multi-conductor system. Post-Processing of the

solutions is performed and the results are linked back to

MATLAB® and stored in a matrix format.

The inductive coupling of the winding turns, along with the

capacitive coupling, forms the resulting SPICE circuit model

which is compared against prototype measurements taken by

Rhode & Schwarz (R&S®) vector network analyzer. (Less)
