HBridge_DC_Drive | H bridge DC/DC converter with DC drive |
HBridge_R | H bridge DC/DC converter with resistive load |
HBridge_RL | H bridge DC/DC converter with R-L load |
Model Modelica.Electrical.PowerConverters.Examples.DCDC.HBridge.HBridge_R
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
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.
