HBridge_DC_DriveH bridge DC/DC converter with DC drive |
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This example of an H bridge with DC drive demonstrates the operation of the DC machine in four quadrants.
The DC output voltage is equal to 2 * (dutyCycle - 0.5)
times the input voltage.
