I was using two op amps with inputs crossed as seen here:
to make inverters for stepping up voltage with high efficiency. The design works well, but op amps seem to be only built for low voltages. I am looking to make a royer converter similar to the one shown here:
Are there op amps or comparators that can run off 120 or 240 volts? If not, why?

There are some op amps, like these ones from Apex that can go up to 50 A or 1200 V, but very expensive (the PA89 costs 716 USD here), and I doubt you really need them.
What exactly do you want to do?
