Heating in 4-1/2 turn inductor
"Jeff Johnson" wrote in message ... "amdx" wrote in message ... Several years ago while making inductors for tuning a class E amplifier we end up with a 4-1/2 turn inductor. The inductor used a 3F3 potcore, gapped I think, but it has been awhile. The inductor was driven hard but below saturation. The problem; the 1/2 turn got HOT. Four turns or five turns were ok. My physicist friend had an EE verify the problem 2000 miles away. So, can anyone tell me why 1/2 turn would make such a difference in the heating? Thanks, MikeK Resonance? (I assume by 1/2 you mean the 4.5 inductor?) Yes, a 4 and 1/2 turn inductor had the 1/2 turn overheat. |
