Description

pict

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.

Inductance
The inductance in henries (H). All finite positive and negative values are accepted, including 0. The default is 0.001.

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 component's width:

⌊     ⌋   ⌊                 ⌋  ⌊ -d   ⌋
   v1        L1  0   ⋅⋅⋅   0      dtdi1
||  v2 ||   ||  0   L2  ⋅⋅⋅   0 ||  || dti2 ||
|⌈  ...  |⌉ = |⌈  ...    ...  ...   ... |⌉ ⋅|⌈   ...  |⌉
   vn        0   0   ⋅⋅⋅  Ln      -din
                                 dt

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:

⌊    ⌋    ⌊                      ⌋  ⌊     ⌋
  v1         L1   M1,2  ⋅⋅⋅ M1,n      ddti1
|| v2 ||    || M2,1   L2   ⋅⋅⋅ M2,n ||  || ddti2 ||
|⌈  .. |⌉ =  |⌈   ..     ..   ..    ..  |⌉ ⋅|⌈  ..  |⌉

Initial current
The initial current through the inductor 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.
Inductor voltage
The voltage measured across the inductor, in volts (V).
