Inductors

Abstract

Inductance is the property that determines a component’s capacity to store magnetic energy and directly affects system dynamics through its impedance, which determines how quickly changes in power flow can occur. The impedance of an inductor, or group of coupled inductors, can be calculated into a matrix, called the impedance matrix. The value of this matrix depends on the geometry, nonlinear magnetic materials and source frequency, which can make analytical solutions very difficult. The impedance matrix is used directly as the modeling tool when performing circuit simulations to predict the effect the inductor has on the rest of the power system.
