AC Current Source
Implement sinusoidal current source
Simscape / Electrical / Specialized Power Systems / Sources
The AC Current Source block implements an ideal AC current source. The positive current direction is indicated by the arrow in the block icon. The generated current I is described by the following relationship:
Negative values are allowed for amplitude and phase. A zero frequency and a 90-degree phase specify a DC current source. You cannot enter a negative frequency; the software returns an error in that case, and the block displays a question mark in the block icon. You can modify the first three block parameters at any time during the simulation.
- Peak amplitude
The peak amplitude of the generated current, in amperes (A). Default is
The phase in degrees (deg). Specify a frequency of 0 and a phase of 90 degrees to implement a DC current source. Default is
The source frequency in hertz (Hz). Default is
60. Specify a frequency of
0and a phase of
90degrees to implement a DC current source.
- Sample time
The sample period in seconds (s). The default is
0, corresponding to a continuous source.
Currentto measure the current flowing through the AC 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.
power_accurrent example uses two AC Current Source blocks in parallel to sum two sinusoidal currents in a resistor.
