RE: Winding primary
Original poster: Terry Fritz <teslalist-at-twfpowerelectronics-dot-com>
Hi Luke,
Simply think of "loss" as how "hot" it gets. The streamers are hot and
account for about 70% of the energy of a coil. The gap is hot and accounts
for the other about 30%. The leads of the caps are pretty darn cold
;-))) and they account for a little more than 0% percent loss....
Cheers,
Terry
