modelSineCurrentVariableFrequencyAndAmplitude
Sine current source with variable frequency and amplitude
Extends from Modelica.Electrical.Analog.Interfaces.OnePort (Component with two electrical pins p and n and current i from p to n), Modelica.Electrical.Analog.Icons.CurrentSource (Icon for current sources).
Information
This current source provides a sinusoidal current with variable frequency f and variable amplitude I,
i.e. the phase angle of the sine wave is integrated from 2*π*f.
Note that the initial value of the phase angle phi defines the initial phase shift,
and that the parameter startTime is omitted since the current can be kept equal to offset with setting the input I to zero.
