I'm not going to bother looking myself but Unitrode came up with some
transformer coupled frequency modulated power/pwm transmission system for
IGBT drive type stuff.

TI bought them so if it is still made then......

Actually I will.... Here you go

UC3727..... New Chip Pair Provides Isolated Drive for High Voltage IGBTs

Whoops, link doesn't work.

Bum, anyway...... If they still make it you might find it.
