Hi Mike,Just count the number of turns you used and multiply the number by 0.65. This is the new number of turns. Or, remove 35% of the turns ;-) 73, Stefan Am 31.05.2010 17:02, schrieb Mike.WE0H: Hi Stefan, How many turns should I wind for a primary side? 8 to 10 maybe?I was using a 48.4 milli-henry primary winding with the secondary at 4.2 henry. There are many primary windings on this transformer but this 48.4 milli-henry winding gave me the highest output voltage on the secondary. 300v p-p with only .7v p-p input.Mike WE0H Stefan S wrote:Mike,Try to use just 65 % of the turns of your primary winding and i bet the optimum will be on 9 kHz! :-)73, Stefan |
