What I'm asking is whether there is anything in the OEM part supply chain that uses the DAB converter instead of IGBTs.

There have been several topologies suggested for SSTs but most being evaluated today are based around the idea of a dual active bridge (DAB) converter. A DAB uses a power bridge to modulate the incoming ac waveform into a high-frequency square wave. The square wave gets passed through a small high-frequency transformer to another power stage. This converter demodulates the square wave and sends it to another inverter which produces low-voltage ac.
