Step down chopper with resistive load
Extends from ExampleTemplates.ChopperStepDown (Step down chopper including control), Modelica.Icons.Example (Icon for runnable examples).
Information
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.
