An Efficient Method of Calculating Inductance Using Near-Field Data

Abstract

Inductance coupling, caused by the mutual inductance between two circuits, is a very important factor in electromagnetic interference(EMI). While calculating the interference of a certain interference source to different locations, the traditional method is to simulate each location separately, which takes too long time and takes up more computer resources. This method is not conducive to the calculation of complex models, especially when it is necessary to calculate the mutual inductance of multiple locations in space. This paper proposes a new calculation method, which can quickly calculate the mutual inductance of the loop in any position on the space based on the simulation results, and save a lot of time while ensuring accuracy of results.
