Purpose

Ideal inductor.

Description

[Picture]

This component provides one or multiple ideal inductors between its two electrical terminals. If the component is vectorized, a magnetic coupling can be specified between the internal inductors. Inductors may be switched in series only if their momentary currents are equal.

Parameters and Dialog Box

Width
The width of the electrical ports resp. the number of ideal 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':

2     3   2                 3  2      3
   v1        L1  0           0      ddti1
66  v2 77   66  0   L2          0 77  66 ddti2 77
64  ..  75 = 64  ..    ..  ..   .. 75   64   ..  75

   vn        0   0          Ln      dtin

In order to model a magnetic coupling between the internal inductors enter a square matrix. The size n of the matrix corresponds to the width of the component. Li is the self inductance of the internal inductor and Mi;j the mutual inductance:

2 v  3    2  L    M            M    3  2 -di 3
6 v1 7    6 M 1    L1;2         M 1;n 7  6 dtd1i 7

  vn        Mn;1  Mn;2          Ln       ddtin

Initial current
The initial current through the inductor 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. The direction of a positive current corresponds to the small arrow in the component symbol.
