Hi,
I am designing a Pulse Transformer for an isolated Thyristor Gate Drive solution and an confused by a detail in calculating the required turns.
I am using the information from the third page here.....
It states that...
N = ET / B.Ac.10^-8
What I dont understand is that I am used to the equation for a square-wave in a transformer being
Bmax = Vin(nom) x 10^8 / 4 x f x N(prim) x Ac
I am assuming that T (first equation) is the pulse time, so actually f (second equation) = 2T.
This would presumably rearrange to
N = Vin x 2T / 4 x f x N(prim) x Ac
and...
N = Vin x T / 2 x f x N(prim) x Ac
My confusion is why I have a 2 here. Is there something I am missing.
