Saturable inductor.

Nonlinear

Description

[Picture]

This component provides a saturable inductor between its two electrical terminals. The inductor has a symmetrical piece-wise linear saturation characteristic defined by positive current/flux pairs.

Parameters and Dialog Box

[Picture]

Current values
A vector of positive current values in amperes (A) defining the piece-wise linear saturation characteristic. The current values must be positive and strictly monotonic increasing. At least one value is required.
Flux values
A vector of positive flux values in Vs defining the piece-wise linear saturation characteristic. The flux values must be positive and strictly monotonic increasing. The number of flux values must match the number of current values.
Initial current
The initial current through the inductor at simulation start, in A. The direction of a positive initial current is indicated by a small arrow at one of the terminals. The initial current default is 0.

Probe Signals

Inductor current
The current flowing through the inductor, in A. The direction of a positive current corresponds to the small arrow at one of the terminals.
Saturation level
The saturation level indicates which sector of the piece-wise linear characteristic is currently applied. During linear operation, i.e. operation in the first sector, the saturation level is 0. The saturation level is negative for negative flux and current values.
