Optic Gate Drivers are the general solution today.

Bodo's Power Magazine out of Germany will give you some ideas if you
pursue the archives.
The magazine is free and anyone on this list will probably find it of value.

You will also find the application notes here of interest:

United's parts are an interesting Cascod that gives it some unique properties.
The start at 650V  and are now available from DigiKey.
Use the four terminal devices to minimize false triggering.
