Step up chopper with resistive load
Extends from ExampleTemplates.ChopperStepUp (Step up 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 up chopper.
DC output voltage is equal to 1/(1 - dutyCycle) times the input voltage.
