I'm not sure on what exactly goes on inside them, but the idea is that you
can maintain a stable output frequency over a range of engine speeds.

with a normal genset, you must run the engine at a fixed speed, even if
there's no load which wastes fuel.

Also, an alternator running at higher speeds can be smaller than one
running slower.

@KNOLOGY.NET:


Here is the EU2000 diagram

with a paragraph at the bottom: Operating Principles describes what's going
on in there.

 Ok that tells me what's going on.
I didn't pay attention at the time but the Yamaha schematic Jim linked to
was
not an inverter generator.
 z, your Honda link is an inverter generator and does rectify AC to power an
inverter.
                                     Thanks for confirming my hunch,

"Inverter System with Pulse Width Modulation - Industry-leading system
produces higher-quality and cleaner electricity. Results in pure sine
wave as clean or cleaner than commercial power and can operate
products with built in microcomputers", or at its name, "Inverter
