H Bridge
H bridge (four quadrant converter)
Description
Connections
Parameters
Modelica Standard Library
The H Bridge (or Half Bridge) component is a four-quadrant DC/DC converter. It consists of two single-phase DC/AC converters which are independently controlled.
If the firing inputs firep and firen are inverses, the two legs are controlled symmetrically so that full positive or negative output voltage can be generated.
To see an example model that uses this component, search for HBridge in the MapleSim search bar on the main toolbar.
