EdIt's my understanding that a magnetron tube acts like a 4 KV Zener diode. You should be able to get about 4 kV DC out of the inverter. I think that the output of the MWO inverter units is already DC. If not, you would have to use high speed, high voltage diodes.
The trick is to get the inverter to run outside of the MWO. I understand that there is a logic level control signal that comes from the microcontroller in the oven to enable the HVPS. Figuring it out might not be trivial, especially if the controller has failed.
I wonder if one of the supplies could be configured to run with reverse polarity output, like some experimenters have done with Spellman HV power supplies for fusor work. Then you could run two of them back to back to get 8 kV at half an amp, which would be a respectable source for a DC resonant charged TC.

I think this may have been discussed here but I wonder if the output of the inverter could be rectified and used to charge the capacitor of a 'DC' excited TC. Easy enough to try for someone with the ambition! As for the iron taking the beating, it's too bad the folks who build the 'good old iron core' transformers didn't put enough iron in them to keep them from getting way too hot on 120V.Ed Scott Moseley wrote:It would be fun to watch the smoke.

Instead of the usual iron brick MOT, it has an inverter as a HV source. Other than scavenging it for parts, is it useful?PBT
