Influences of shields to the inductance with transient currents

Frequency of currents, material properties and physical shapes can influence the inductance. Especially for the transient current and linear medium, the current density may vary greatly to change the inductance. Based on the analysis of inductance calculation, a transformer model is introduced to illustrate the contributions of parameters to inductances. Numerical experiments are given to verify the results using software ANSOFT Maxwell SV. The results show that influences of the shields to the inductance with certain transient currents can be neglected.
