RE: [TCML] More wire better?

["Lau, Gary" <Gary.Lau@xxxxxx>]

If you are attempting to raise Q by increasing the numerator of circulating-power / loss-per-cycle, wouldn't increasing the tank capacitor value accomplish this as well?  The question then becomes do inductor losses increase more slowly with inductance, vs. capacitor losses with capacitance.  And to further complicate things, I think one must also consider what happens to the losses in the other tank component - if you maximize Q in the inductor, what have you done to the Q of the capacitor by forcing it to some extreme value?  Correct me if I'm mistaken, but I'm assuming that it's the combined Q of the tank circuit that matters.  I don't myself know the answer and was wondering if you had evidence of one or the other.

The answer however is academic, as there are many more variables and constraints involved.  The primary capacitance must be selected to match the charging capability of the power supply, and this takes precedence over Q.
