Current Source
The Current Source () feature connects a current source between two nodes in the electrical circuit.
Node Connections
Set the two Node names for the connecting nodes for the current source. The first node represents the positive reference terminal from where the current flows through the source to the second node.
Device Parameters
Enter the Source type that should be adapted to the selected study type. It can be General source, AC-source, or a time-dependent Sine source or Pulse source. Depending on the choice of source, also specify the following parameters:
•
For a General source, the Current isrc (default value: 1 A). General sources are active in Stationary, Time-Dependent and Frequency Domain studies.
•
For an AC-source: the Current isrc (default value: 1 A) and the Phase Θ (default value: 0 rad). AC-sources are active in Frequency Domain studies only.
•
For a sine source: the Current isrc (default value: 1 A), the Offset ioff (default value: 0 A), the Frequency (default value: 1 kHz), and the Phase Θ (default value: 0 rad). The sine sources are active in Time-Dependent studies and also in Stationary studies, providing that a value for t has been provided as a model parameter or global variable.
•
For a pulse source: the Current isrc (default value: 1 A), the Offset ioff (default value: 0 A), the Delay td (default value: 0 s), the Rise time tr and Fall time tf (default values: 0 s), the Pulse width pw (default value: 1 μs), and the Period Tper (default value: 2 μs). The pulse sources are active in Time-Dependent studies and also in Stationary studies, providing that a value for t has been provided as a model parameter or global variable.
All values are peak values rather than RMS.
For the AC source, the frequency is a global input set by the solver. AC sources should be used in frequency-domain studies only. Do not use the Sine source unless the model is time dependent.
