And that completely undoes two of the three factors in AC’s favor. (And efficient DC-DC converters kill the transformer.) No, we don’t think that there’s going to be a switch overnight ...

For this discussion, the flyback converter used in portable AC-DC supplies is simplified with a new semiconductor material—a gallium-nitride (GaN) high-electron-mobility transistor (HEMT).

One significant area of research is the development of fault-tolerant converter topologies. For instance, a novel topology-reconfigurable AC-DC converter has been proposed, which can switch ...
