Package Modelica.Electrical.Spice3.Sources
Time dependent SPICE3 voltage and current sources

Information

This package contains the SPICE sources.

Note: There are differences between SPICE3 and Modelica concerning the default values of the parameter. Therefore it is recommended to specify all parameters of the source.

Model Modelica.Electrical.Spice3.Sources.V_pwl
Piece-wise linear voltage source

Information

This model generates a voltage by linear interpolation in a given table. The time points and voltage values are stored in a matrix table[i,j], where the first column table[:,1] contains the time points and the second column contains the voltage to be interpolated. The table interpolation has the following properties:

The time points need to be monotonically increasing.
Discontinuities are allowed, by providing the same time point twice in the table.
Values outside of the table range, are computed by extrapolation through the last or first two points of the table.
If the table has only one row, no interpolation is performed and the voltage value is just returned independently of the actual time instant, i.e., this is a constant voltage source.
The table is implemented in a numerically sound way by generating time events at interval boundaries. This generates continuously differentiable values for the integrator.

Example:

   table = [0  0
            1  0
            1  1
            2  4
            3  9
            4 16]
If, e.g., time = 1.0, the voltage v =  0.0 (before event), 1.0 (after event)
    e.g., time = 1.5, the voltage v =  2.5,
    e.g., time = 2.0, the voltage v =  4.0,
    e.g., time = 5.0, the voltage v = 23.0 (i.e., extrapolation).
