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 down chopper. DC output voltage is equal to dutyCycle times the input voltage. Plot current currentSensor.i, averaged current meanCurrent.y, total voltage voltageSensor.v and voltage meanVoltage.v.
