Controlled Current Source (Three-Phase)

Ideal three-phase controlled current source

  • Library:
  • Simscape / Electrical / Sources

  • Controlled Current Source (Three-Phase) block

Description

The Controlled Current Source (Three-Phase) block represents an ideal three-phase current source that is powerful enough to maintain the specified current through it regardless of the voltage across it. The output currents are [ia ib ic] = S, where S is a vector containing the numerical values presented at the physical signal port.

The figure shows the equivalent circuit for the expanded implementation of the Controlled Current Source (Three-Phase) block.

To use the Controlled Current Source (Three-Phase) block as an abstracted current controller in an electrical drive, connect the conserving ports for the output current directly to the machine.

To access the variant implementation with an expanded, three-phase port, right-click the block and select Simscape > Block choices.
