Subject: LF: Microwave oven transformers

 

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 lam= inations 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 primarie= s 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 app= liance operators.

 

Regards

Ken Wright
