Hello,
I have a transformer 8 turns primary 240 turns secondary ETD29 core PC44 material running at 30 kHz 14.2 V input I calculated primary turns using the formula/equation (14.2)(10^8)/(4)(30,000)(1800)(5)=1.3 turns primary so I am way over the required number of primary turns however in theory that would prevent the windings from getting hot right? At a steady 4.5 amps the windings get very hot to the point where you can't keep your fingers on them for more than a second or two. Meanwhile the core heats up but significantly less any idea what's going on or how I can solve this problem? I have no air gap currently.
