Comparison of Three-Phase Port Types
This example shows a comparison of Composite three-phase ports versus Expanded three-phase ports. The first circuit shows a Voltage Source configured with a Composite three-phase port. A Phase Splitter block provides the interface to the Simscape™ foundation library electrical elements. The second circuit shows a Voltage Source configured with an Expanded three-phase port which can connect directly to the Simscape foundation library electrical elements. The Voltage Source can be changed from Composite to Expanded three-phase ports by use of the Modeling option mask parameter.
Both circuits are equivalent. Both consider instantaneous three-phase voltages and currents. Both give the same results.
