DC Current Source

Ideal constant current source

  • DC Current Source block

Simscape / Foundation Library / Electrical / Electrical Sources


The DC Current Source block represents an ideal current source that is powerful enough to maintain specified current through it regardless of the voltage across the source.

You specify the output current by using the Constant current parameter, which can be positive or negative.

The positive direction of the current flow is indicated by the arrow.
