Hi,
I made some ferrite rod inductors, about 10 turns of 14 AWG wire on the rod gives about 5uH and a Q factor of ~30 or so, while 260 turns of
38AWG litz wire (14AWG equivalent) gives a Q approaching 90 or so, both at a measurement frequency of 15.6kHz. This inductor will have about 1 amp of current ripple through it at about 200kHz, (rough estimation) and about 12Amps DC current. How can the power losses of the inductor be calculated from the Q factor and this AC current information?
cheers, Jamie
