Hey-Hey!!!,
I am prepering to test a choke for DC tolerance and self resonance.

For pure AC inductance, I am going to use 60cps because it is easy. A resistor in series, to determine AC current( from teh department of redundancy department ). {V-inductor/V-resistor} times {R/2Pi60}=inductance in Hy.

An adjustable current regulator with DC voltage supply greater than V-ac peak-to-peak ought to allow me to determine its DC tolerance. Say a 40 vac signal and a 200VDC supply feeding the current regualtor. Might have heat issues with the CCS, but that's OK, I can deal with that.

Any suggestions at improving this method?
regards,
Douglas
