Well, that is their design intent - microwave ovens are basically a half wave doubler, with the second diode formed by the magnetron.
I've seen people build fairly impressive stacks (10 stages) of microwave oven diodes and capacitors - the challenge is that if you suddenly discharge it (like you draw a spark from the top of the stack), you often destroy a bunch of diodes, because of the high peak curent.
So a good experiment if you have a lot of cheap HV diodes.

If not, why?They're designed to filter line frequency (50/60 Hz) and have high loss at 100kHz+ TC frequencies. Most also have a bleeder resistor built in that is parallel to the capacitor. For a voltage doubler at line frequency, though, they work just fine. _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxxxxxx https://www.pupman.com/mailman/listinfo/tesla_______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxxxxxx https://www.pupman.com/mailman/listinfo/tesla
