Do they exist? To quote George Bush "I heard rumours on the internets" that they might.

If you are looking for "Zero voltage switching" (ZVS), you did not look very hard. Look at Texas Instruments, Fairchild Semi, On Semi and ST micro, they are the big suppliers. Cheers, Harry
I'd probably use a microcontroller, as I often do for things such as PID zero-voltage switching temperature control, but if you don't like that answer you could simply use a "PWM" circuit driving a zero-voltage switched optoisolator or SSR.

micro,
Include International Rectifier as well. They are specialists in ZVS IC's and MOSFETS, eg.
