Modelica.Electrical.MultiPhase.Sources

Information

This package contains time-dependend and controlled multiphase voltage and current sources:

• SignalVoltage: fed by Modelica.Blocks.Sources arbitrary waveforms of voltages are possible
• SineVoltage : phase shift between consecutive voltages by default = pi/m
• SignalCurrent: fed by Modelica.Blocks.Sources arbitrary waveforms of currents are possible
• SineCurrent : phase shift between consecutive currents by default = pi/m
