Can anyone point me to a technical reference that discusses dielectric heating (not magnetic flux related) due to high VSWR in the ferrite core of a balun or common mode choke? Thanks much, Dave Ab

I remember, though, previous discussions here on TowerTalk where more knowledgeable people than either you or I pointed out that damaging core heating in a typical ferrite balun or common mode choke
I was referring to a balun with that statement. Dave AB7E I remember, though, previous discussions here on TowerTalk where more knowledgeable people than either you or I pointed out that damaging c
Balun/common mode choke what is the difference? Neither should be magnetizing the core unless you are talking about a magnetically coupled transformer like the isolation transformer in an FCP system.
A common mode choke is one form of balun. A different device is the voltage balun, which is commonly seen in ham radio catalogs. It is flux coupled and does involve "magnetizing inductance". Actually

Ok -- here is a suggestion -- if the question is what is causing the cores to heat .... some "electric field" or ampere turns magnetizng flux. Make a short piece of bifilar transmission line - parall
Got sent by accident -- I would not try this except with a rugged tube amp and watch it carefully feeding the series resonated caseThe core may heat very rapidly . I had decided to not send it . I di
Hi, Hank. Well, I have various very high power resistors, so by using them in various combinations with some large variable capacitors I can generate various VSWR loads. I can measure the actual R +
