Description

Block Current Source (Three-Phase) simulates an ideal three-phase current source that supports sinusoidal currents of a given magnitude regardless of the voltage on it.

The output current is determined by the following equations:







where

  • — the amplitude of the phase current;

  • — RMS value of the phase current;

  • — corresponding phase currents;

  • — frequency;

  • — phase shift;

  • — the time.

The arrow indicates the positive direction of the current. The source is connected by a star, and port n corresponds to the neutral point.
