** That explanation is highly simplistic.

A crucial thing with a microwave oven is that the current drawn from the
HV
transformer is the same on both half cycles of the AC supply - otherwise
the iron core saturates and that would blow the AC fuse.

Wouldn't it make more sense to use a switcher supply now-a-daze?

** Nope.

The ovens I've seen had large ergo $$$ transformers.


** Made in China for about $1 or $2 each and normally way outlast the rest
of the oven.

Any 1kW SMPS that does the same job is gonna cost 20 times more and be the
first thing to fail.
