Variable Resistor with Constant Series Inductor

Purpose

Variable resistor with constant series inductor.

Library

Nonlinear

Description

[Picture]

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]

Width
The width of the electrical ports resp. the number of resistors/inductors represented by the component.
Inductance
The inductance in henries (H). All finite positive and negative values are accepted, including 0. The default is 1.

If the parameter is a scalar, all internal inductors have the same inductance. To specify individually the inductances in a vectorized component use a vector [L1 L2:::Ln] . The length n of the vector must correspond to the parameter 'Width'.

Initial current
The initial current through the component at simulation start, in amperes (A). This parameter may either be a scalar or a vector with 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 A. The direction of a positive current corresponds to the small arrow at one of the terminals.
