HBridge

 Description The H-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 ${\mathrm{fire}}_{p}$ and ${\mathrm{fire}}_{n}$ 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.
