Transformer calculation abbreviations question
« on: May 15, 2017, 01:48:27 pm »
In this quotation what do the abbreviations stand for when calculating transformer turns ratios please?

"I just use whatever feels right and apply the V < 4.44F.N.A.B  absolutely rigorously, keeping B to less than 0.1 usually"



Thanks.
Best regards,

F = frequency.
N = number of turns.
B = flux density.
A = cross-sectional area of core.
Note, the formula only applies to sine waves.
