Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Plot current currentSensor.i[:], harmonic current magnitude fundamentalWaveCurrent[:].y_RMS, harmonic voltage magnitude fundamentalWaveVoltage[:].y_RMS. The instantaneous voltages voltageSensor.i[:] and currents currentSensor.i[:] directly show the switching pattern of the inverter. There is not smoothing effect due to an inductance in this example; see PolyphaseTwoLevel_RL.
