[ARC5] 800 Hz Static Inverters

[J. Forster]

I want to power up parts of an ASB-5 RADAR. The thing takes 800 Hz, either
80 or 115 VAC, Single Phase, roughly 500 - 1000 Watts.

The two preferred options would be:

A commercial Static Inverter, like an Elgar or equal
A Screaming Mimi rotary inverter.

But, neither are really practical for me.

I've read articles on the web about modifying commercial (Asian) 60 Hz
units for 400 Hz. This seems a possible alternative, but the articles
referred to obsolete and unavailable converters.

Does anybody know of suitable 'true sinewave' 60 or 800 Hz inverters that
are currently available (used OK) that have documentation available? My
guess is that not only the internal clock, but also any output filters,
would need modifying.

Alternately, does anyone know if there are 1 Phase VFDs that are line
powered that can be used as an inverter?

Thanks,

-John
