2873 2009-04-06 12:06:46 Stan Toroid link coil placing question

Does it make any difference in the efficient of a link (secondary) coupling where the link is placed in relationship to the hot (Rf end) or cold (power or ground end) of the primary inductor? The coils are wound on a T50-2 toroid.

Thanks, Stan ak0b

Stan:

Inter winding capacitance will have less effect if you
wind it on the cold end. That is, the winding to winding
voltage will be less, so less parasitic coupling.
