Controlled Current Source
Implement controlled current source
Library
Simscape / Electrical / Specialized Power Systems / Sources
Description
The Controlled Current Source block converts the Simulink®input signal into an equivalent current source. The generated current is driven by the input signal of the block. The positive current direction is as shown by the arrow in the block icon.
You can initialize the Controlled Current Source block with a specific AC or DC current. If you want to start the simulation in steady state, the block input must be connected to a signal starting as a sinusoidal or DC waveform corresponding to the initial values.
Note
The Simulink input signal must be a complex value (phasor) when you are using the Controlled Current Source block in a phasor simulation, because in this case,Simscape™ Electrical™Specialized Power Systems software does not automatically convert the input signal from time-domain into complex (phasor) signal.
Parameters
- Initialize
-
Default is selected. If selected, initializes the Controlled Current Source block with the specifiedInitial current,Initial phase, andInitial frequencyparameters.
- Source type
-
TheSource typeparameter is not visible if theInitializeparameter is not selected.
The type of current source. Select
AC
(default) to initialize the Controlled Current Source Block as an AC current source. SelectDC
to initialize the Controlled Current Source block as a DC current. - Initial amplitude
-
This parameter is not visible in the dialog box if theInitializeparameter is cleared. The initial peak current for the initialization of the source, in amperes (A). Default is
0
. - Initial phase
-
The initial phase for the initialization of the source, in degrees. Default is
0
. TheInitial phaseparameter is not visible in the dialog box if theSource typeparameter is set toDC. - Initial frequency
-
The initial frequency for the initialization of the source, in hertz (Hz). Default is
0
. TheInitial frequencyparameter is not visible in the dialog box if theSource typeparameter is set toDC. - Measurements
-
Default is
None
. SelectCurrent
to measure the current flowing through the Controlled Current Source block.Place a Multimeter block in your model to display the selected measurements during the simulation. In theAvailable Measurementslist box of the Multimeter block, the measurement is identified by a label followed by the block name:
