Why is it called an invertor?

Typical microwaves use fixed AC power to drive the magnetron.
Inverter driven magnetrons use DC power, which can be variable.


Wrong.

Both styles actually take AC incoming mains, raise it to 5k or so,
and convert it with a single diode mind you, to DC to feed the
magnetron. The filament is fed by low voltage AC. Neither of them can
or do vary the voltage going to the magnetron. That's just not how it
works. You can't lower the voltage to reduce microwave energy. And
you can't raise it to get more microwave energy, either. The
magnetron requires voltage within a certain range to function. More
than that will burn the magnetron up. Less will prevent it from
making viable microwaves.

So what we need is a bigger ****ing magnetron. More power! Get one from Binford!
