Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

The H bridge is a four quadrant DC/DC converter. It consists of two single-phase DC/AC converters which are controlled differently; see Fig. 1.

**Fig. 1:** H bridge

If the firing inputs fire_p and fire_n are inverse, the two legs are controlled symmetrically so that full positive or negative output voltage can be generated. See examples DCDC.HBridge.
