Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This example demonstrates the switching on of an R-L load operated by an H bridge.
DC output voltage is equal to 2 * (dutyCycle - 0.5) times the input voltage.
Plot current currentSensor.i, averaged current meanCurrent.y, total voltage voltageSensor.v and voltage meanVoltage.v. The waveform the average current is determined by the time constant L/R of the load.
