Model Modelica.​Electrical.​PowerConverters.​Examples.​DCDC.​HBridge.​HBridge_R
H bridge DC/DC converter with resistive load

Information

This example demonstrates the switching on of a resistive load operated by an H bridge. DC output voltage is equal to 2 * (dutyCycle - 0.5) times the input voltage. Plot current currentSensor.i, averaged current meanCurrent.y, total voltage voltageSensor.v and voltage meanVoltage.v.

Model Modelica.​Electrical.​PowerConverters.​Examples.​DCDC.​HBridge.​HBridge_RL
H bridge DC/DC converter with R-L load

Information

This example demonstrates the switching on of an R-L load operated by an H bridge. DC output voltage is equal to 2 * (dutyCycle - 0.5) 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.
