Variable Resistor with Constant Series Inductor

Purpose

Variable resistor with constant series inductor.

Library

Nonlinear

Description

pict

This component models a variable resistor with a constant inductor connected in series. The resistance is determined by the continuous signal fed into the input of the component.


Note  This component is based on a voltage controlled current source. It may therefore not be connected in series with other current sources or inductors.

Parameters and Dialog Box

[Picture]

Inductance
The inductance in henries (H). All finite positive and negative values are accepted, excluding 0. The default is 1e-3.

In a vectorized component, all internal inductors have the same inductance if the parameter is a scalar. To specify the inductances individually use a vector [L1 L2 ...Ln]  . The length n   of the vector determines the width of the component.

Initial current
The initial current through the component at simulation start, in amperes (A). This parameter may either be a scalar or a vector corresponding to the width of the component. The direction of a positive initial current is indicated by a small arrow in the component symbol. The default of the initial current is 0.

Probe Signals

Inductor current
The current flowing through the inductor, in amperes (A). The direction of a positive current is indicated with a small arrow in the component symbol.
