Transformer core cross-sectional area calculation formula

(1) Transformer silicon steel sheet cross section: 3.2CM*3.4CM*0.9=9.792CM^2 (2) Calculate transformer power based on silicon steel sheet cross section: P=S/K^2=(9.79/1.25)^2=61.34 watts (take 60 watts) (3) Calculate the number of turns per volt of the coil based on the cross section: W=4.5*10^5/BmS=4.5*10^5/(10000*9.79)=4.6 turns/volt
