Step down chopper
This is a conventional step down chopper model. It consists of a transistor and free wheeling diode.

H bridge (four quadrant converter)
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.
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.
