Hi,
I am trying calculate C1 and C2 capacitors for my coil.
Coil parameters:
Ls@100kHz/1Vrms = 12.74uH
Rdc@100kHz/1Vrms = 1.12 Ohm
In equations at 28page of BQ51003 datasheet is Ls' and Ls.
I understood Ls' is measure with transmiter, is it correct?
How should I measure Ls' without correct values of capacitors in final system?
I also calculate values from datasheet of BQ51003EVM. There are C1 = 183nF, C2 = 1,9nF. Transforming equation 6 for C1 and C2 I get Ls' = 13,85uH and Ls'~= Ls but from WR-483250- 15M2-G Coil datasheet Ls = 10,5 uH @100kHz/Vrms=1V.
What is good way to calculate correct Ls', C1 and C2 values?
