Freebeard, those two things are apples and oranges. "Dual active bridge" is a topology for connecting multiple switching devices - think of it as a road map for putting the pieces together. "IGBT" stands for insulated gate bipolar transistor. It's a specific type of one of those pieces - the switching device.
So you could use IGBTs to create a DAB converter. Or you could use another type of device - say a MOSFET or even a bipolar junction transistor (BJT). At the company I used to work for, we did a pretty detailed paper design for a solid state transformer that used IGBTs. We built some of the subassemblies and tested them, but ran out of funding before we put it all together.
