I have one of these and AFAIK only Panasonic is using it. 'Genius' is their
trademark, inverter technology is not. It's a very powerful switchmode power
supply that varies the input power to the microwave. BTW, don't buy the
convection version - they are a swine to keep clean.

All other makes I know of cycle power to control cooking which does not work
as well for some items (oatmeal for one).

The sample I have drives both the magnetron high voltage and filament
from the same transformer. I would think this is hard on the magnetron
at moderate power where the filament isn't as hot as it should be but
perhaps it's not a big issue.
