Has anyone here ever used a toroid for a filter choke in a HV supply successfully?

I have not tried this but can speak to this, theoriticaly .... since a torroidal core is not gapped unless it is a bigger 'c' core then the winding would act as a swinging choke .... the typical ungapped EI core swinging choke has a 5:1 inductance change (ex: 25-5 H swinging choke) but what I don't know is if a toroidal winding would swing more-the same-or less than the ungapped EI core ... it is possible it would have higher harmonic content ....a good question

Primarily hypothetical at this point since I found a conventional choke thanks to one of the gentleman on this forum... Smiley
