Sourcing ferrite cores for HV transformers.
Greetings.
I am building 2KV power supplies for which I need Qty 6 UU cores the type used in HT generators for CRTs. I have had no luck finding them in catalogs of local distributors. I am in Ireland so a European and preferably UK supplier is what I need. Ferrites in general are easy enough to get. My difficulty is finding UU cores specially designed for HT transformers. Listings of UU cores I have found seem to be rectangular cross section whereas those intended for HT have round section to facilitate the construction of the HT winding. I suspect these there is very limited demand for these items outside China or whereever our TVs are made these days. As a possible alternative approach does anyone know a manufacturer building high voltage equipment? I could beg some! The size is aproximately 33 mm inside; 55 mm outside giving a diameter of ~12mm for each of the two core "legs". I don't know the exact ferrite type except they are to make a 2KV step up transformer. I succesfully used cores from old TVs before, but the modern ones are all potted so I can't use them. I would be very grateful if somebody could point me to a supplier. Regards Joseph Casey. |

IIRC Philips (FERROXCUBE) was the big supplier in Europe. http://www.amidoncorp.com/ N |
