Hi,
I have been trying to figure out how the inductance factor (physically, proportional to the core gap distance) has an effect on the flux density of a transformer in operation as per faradays law:
B = (Vin x 10^8) / (4.44 x freq x Ae x Np)
Ae is core area, and Np is primary turn number. This calculation is for a sine wave.
The inductance factor (Al ill call it) is not in this equation, but I know that if I were to gap the core (which changes Al), that would change the flux density. The BH curve would get streched out and id loose efficiency but I'd be able to avoid saturation in certian cases. So, I know that B changes if I change Al, but Al is not in the equation. Can anyone shed some light on this for me...I know its in there somewhere, I just cant see it...
