Using 1/2 wave rectification on each one will result in big DC

Hey, Tim -

IIRC, there is only one diode attached to the transformer in my
microwave. That would mean it is half-wave rectified as it comes from
the factory. Yes?

Yes, come to think of it -- yes. Perhaps the core is sized to take it.

I guess the next question is how much harder can you push the system if
you _aren't_ putting DC on the core?


Do they not put a capacitor in series with the transformer secondary, and
then connect this combination to a diode in parallel with the magnetron?
In this way the capacitor would prevent DC in the transformer.
