RE: eddy current with secondary coil



Original poster: "Lau, Gary" <gary.lau-at-hp-dot-com> 

Space-winding a secondary coil will result in one with a higher Q, but Q is 
simply not all that important on the secondary.  I suspect the 
"requirement" of close winding a secondary is more from the lower (than 
needed) inductance that is achieved when space winding.  Of course, one may 
add more turns to compensate, but this changes the aspect ratio, so it's 
difficult to make an apples to apples comparison.

hi all,

If the proximity effect of the secondary wires is causing higher eddy
currents within the wire, increasing reactance at high frequency, then it
would make sence to space the turns out on the secondary form so that more
energy will flow though the wire, which suggests higher output. Though this
can't be true since close turns is what is required ?
