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