I think I posted before that Siemens manufacturers low voltage version of the same inverter I (and others) use now. Something like 65V...180V range or similar. So yes AC drive doesn't *have* to be high voltage, it's just you take maximum advantage of this technology when the voltages are relatively high and currents - low.
