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
