Sorry Ken,

 

I did not mean to trivialize or be facetious but microwave transformers do have a reputation for biting.  I will refrain from further obvious comments!!  J

Jim.

There will probably be a fair bit of technical smoke comimg out of Luton, but that is what our hobby is all about, any other usefull sugestions?

Hello everyone.

Does any one have experience in using microwave oven transformers in high voltage power units, I acquired two of these at the weekend. I was informed that as they stand the voltage regulation is poor, to improve this the 'Core Shunts' should be removed, (these are laminations between the two stacks), removal of these 'shunts' also has the effect of considerably increasing the magnetisation current. The solution to this seems to be to use two transformers, connecting the both primaries and secondary's in series to restore the 2KV output voltage.

 

Any comments on this most welcome

 

Note for Mal, this is serious stuff not for appliance operators.

 

Regards

Ken Wright
