Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This example demonstrates the switching on of a resistive load operated by a step up chopper.
DC output voltage is equal to 1/(1 - dutyCycle) times the input voltage.
Plot current currentSensor.i, averaged current meanCurrent.y, total voltage voltageSensor.v and voltage meanVoltage.v.
