Okay, here's a look at the UcD that's currently running on the test-bench, I opted to redo the driver stage with pre-driver dead-time control and a transistor right across the MOSFET to force it to switch off rather than wait for the MOSFET to make up his mind and switch.
Don't laugh at the layout as I just had to mount some of the components in the air because they didn't fit the 'lochraster' anymore. The resulting carrier frequency waveform is quite nice though, considering the less than ideal layout.

As usual comments are most welcome!
