      The power setting makes the microwave cycle between ON and OFF at the given ratio. So at 50% power the microwave will only be heating for half of the cook time.

          Nope, pretty much all have a duty cycle. Like 30 seconds on, 10 seconds off, and they keep repeating that or similar for however long the cook time is. If you listen closely you can hear the magnetron kick on and off.

          I believe Panasonic was the only company that sold an inverter microwave that lowered the power output.

        Modern LG microwaves have a variable power inverter so it’s not PWM. I would imagine they’re not the only ones.
