See:
http://en.wikipedia.org/wiki/Inverter_(electrical)
In the early days of car radios an inverter using a mechanical vibrator changed the DC input to AC to drive a transformer to boost the voltage to that required by the receiver vacuum tubes. Of course that high voltage AC, pretty much a square wave, was rectified by tube diodes, filtered, and used by the radio.
There were inverters made to provide AC output from DC to power AC input devices.
There were also dynamotors that were a combined DC motor and DC generator for converting low voltage, 6 or 12 or 24 VDC, to maybe 500 V DC for powering transmitters and receivers. One of these was the PE-103.

The output of your inverter may be used as AC power or it may be rectified and filtered to provide high voltage DC.

Gar...Thanks for your response. So if I'm understanding this correctly then the constant potential high frequency inverter generator would ensure the output voltage remains largely unaffected by power source fluctuations on the medical equipment therefore keeping the voltage at a constant level. I am correct? Basically does it act as a power conditioner?

Also I would conclude that the output is a regulated voltage.
This would probably be defined as a switching regulator that includes a transformer to produce a high voltage. This supply might monitor the output voltage as a part of the feedback path, best regulation. Or maybe the monitoring is on the primary side, regulation not as good.

I think there may be a different interpretation for this, given the context. Is this medical device an electrocautery/electrosurgery unit? If so, the term is referring to a "generator" in the sense of a "signal generator" - a high frequency inverter with constant output voltage which is used to cut and seal tissue electrically.
