Model Modelica.​Electrical.​PowerConverters.​DCDC.​HBridge
H bridge (four quadrant converter)

Information

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.
