If you search the class-D power amp modules available for the audio
market I think you may find what you need off the shelf.
Steve
100 amps and 500 watts implies a load impedance of 0.05 ohms. Some
professional audio amplifiers may handle this, but I think most will
go into self-protect mode.
Best bet might be a car amp:

If Levente is just looking for a sine wave, he should check out
variable frequency drive motor controllers. Search ebay for "VFD".
