Implement controlled current source
Fundamental Blocks/Electrical Sources
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 needs to be a complex value (phasor) when you are using the Controlled Current Source block in a phasor simulation, because in this case, Simscape™ Power Systems™ software does not automatically convert the input signal from time-domain into complex (phasor) signal.
If selected, initializes the Controlled Current Source block with the specified Initial current, Initial phase, and Initial frequency parameters.
The Source type parameter is not visible if the Initialize parameter is not selected.
The type of current source. Select
AC to initialize the Controlled Current Source
Block as an AC current source. Select
DC to initialize
the Controlled Current Source block as a DC current.
The Initial current parameter is not visible in the dialog box if the Initialize parameter is not selected. The initial peak current for the initialization of the source, in amperes (A).
The initial phase for the initialization of the source, in degrees. The Initial phase parameter is not visible in the dialog box if the Source type parameter is set to DC.
The initial frequency for the initialization of the source, in hertz (Hz). The Initial frequency parameter is not visible in the dialog box if the Source type parameter is set to DC.
Current 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 the Available Measurements list box of the Multimeter block, the measurement is identified by a label followed by the block name:
uses a Controlled Current Source to generate a 60 Hz current modulated
at 5 Hz.
Simulation produces the following waveforms:
