Document Type and Number:
Japanese Patent JP7159068
Kind Code:
B2
Abstract:
To make it possible to conduct inductance analysis efficiently.SOLUTION: In an inductance analysis system, an inductance analysis method calculates a magnetic permeability distribution in a time step of each element included in a nonlinear magnetic substance region of an electric apparatus composed including a nonlinear magnetic substance and a coil by nonlinear transient magnetic field analysis. The inductance analysis system performs linear magnetic field analysis using the magnetic permeability distribution at a certain time step before updating the time step from the certain time step to a next time step. The inductance analysis system calculates an inductance matrix component regarding a coil in a certain time step based on analysis results by linear magnetic field analysis.SELECTED DRAWING: Figure 2
