For what it's worth, Yamaha make an EF1000 and an EF1000iS Nowhere in the manual below do I see the words inverter generator, but I do agree there is some evidence to support the idea that it is.
EF1000
The model # on the title page is clearly the inverter version, and the schematic shows a stepper throttle control.

Just a little healthy skepticism mixed with an interest to know. Here I wasn't skeptical enough. My new stainless steel glove $7.99
One of my teachers, years ago asked "What is a rotating mechanical rectifier?".
When we gave up, he answered "A commutator and brushes".
I've never forgotten that.
Here's an easy one: What is the difference between a generator and alternator?

Search for the word "inverter". I found it twice, once there and once for connected devices. In the Foxit pdf reader Search is under Tools.

But it has to be 320VDC, not 160. Actually, that'll probably blow one = capacitor (and might reverse the other one!).
I can't imagine PFC supplies would have a problem, though some = controllers may get confused without AC input. If they stop PFC-ing, = voltage drops out and you get the same problem as before. Most of those = run at 400VDC link, so you'd need even more in that case.

Let's not get too cute. A comb or rug can generate DC electricity too. Tesla cured us of the DC habit.

That's because the phrase is "inverter control unit", which is the blank box in the middle of the schematic that the 3 phase AC goes into and the single phase AC comes out of. Look under "Overload Indicator Light".
You normally don't read manuals until you've bought the product, if even then, so they are free of marketing department foofoo.
I have to write some sort of manual for most everything I design.

Ok, but only one of those counted. Mike PS. I'm no long a skeptic. :-)
That's funny, I thought it was a rotatary mechanical inverter. ;-)

how about 3 cheers to Yamaha for publishing this stuff!!
HOnda is so stingy they want 30 bucks for the service manual (which I paid .. I know I bitch about this all the time, but I feel no remorse for scanning that dang thing. It's just lame as hell to withhold information from someone who's bought three of those things over the years.) Zero useful manuals for honda are on line from the official site that I could ever find.

Ah ha!
But those are also AC generators, simply using electrostatic rather than = magnetic induction. You still need a commutator to make DC. ;-)

ooops Electrostatic charges are DC!
When they discharge the electron "inertia" usually makes them overshoot the equalibrium and then over shoot back giving an AC with high frequencies and lots of RFI.
ready for the RFI coming?

A Wimshurst machine generates DC from a rotor without a commutator.

Synchronous rotary rectifier.
No...the generator is upside-down!
How about a DC motor, in a rotating reference frame?

You do mean service manual when you say service manual, right? Ya, I thought so.
Anyway here's the owners manual to the Honda EU6500isa.

The Faraday disk is weird. I didn't expect statement 2 or 3. So much for relative motion.
========================================= 1. The magnet is held to prevent it from rotating, while the disc is spun on its axis. The result is that the galvanometer registers a direct current. The apparatus therefore acts as a generator, variously called the Faraday generator, the Faraday disc, or the homopolar (or unipolar) generator.
=========================================
