A halfbridge usually has two switches and two capacitors to maintain a middle voltage between the positive and negative of the DC- bus. So what you posted is a halfbridge. The transformer works with one primary winding.

A push-pull usually has two windings on the primary, so polarity is switched by energizing the two windings alternately.
