Hello guys,
I have built a coil with the following parameters: inductance L= 288mH, parasitic resistance R=15.5 Ohm, self resonance frequency Fsr=50KHz
The AMETEK 3001iX programmable power supplier is used to supply the power for this coil.
At high frequency, the coil's impedance is dramatically increased, thus the current through the coil become very small with the same applied voltage.
In order to maintain the high current at desired frequency, I use the series RLC resonant effect at desired frequency, therefore some capacitors to connect to the coil in series, which values are chosen from this eq.
C=1/(L*(2*pi*f)^2)
The point is when I connect the capacitors to the coil, the current did not increase as my calculation! It seem did not work with DC sine wave power.
I did try with AC power, however, I seem to be not as expected!
Is there anyone has experience with the resonant circuit, please give me some advice about this problem!
Thank you so much.
