Description

pict

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

Parameters

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.
