This example demonstrates the switching on of an R-L 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. The waveform the average current is determined by the time constant L/R of the load.
