It can be obtained according to the transformer calculation formula. Calculate the number of turns per volt based on the core magnetic permeability (between 6000 and 12000 Gauss) and the core column cross-sectional area (C㎡). Conservatively select the core magnetic permeability. At 10000 Gauss:
N=45/S
(N=turns per volt, S=cross-sectional area of ??core pillar)
Calculate secondary winding When considering leakage inductance and copper loss, a 5% margin of turns must be added.
Current calculation:
I=P/U
(P=power, unit: W, U=voltage)
Line Diameter calculation:
D=1.13×square root (I/δ)
(D=wire diameter, δ=current density of copper wire, select 2.5~3A per square, generally Press 2.5A to select)
