Detailed explanation of common order winding method of transformer
The general single output power supply, the transformer is divided into three windings, the primary winding Np, the secondary winding Ns, the auxiliary power winding Nb, the order of winding is: Np--Ns--Nb, as shown below
Detailed explanation of common order winding method of transformer

The winding method is simple, easy to control various parameters of the magnetic core, has good consistency, low winding cost, and is suitable for mass production, but the leakage inductance is slightly larger, and the coupling capacitance is small, and the EMI is better, so it is suitable for For small power applications that are not sensitive to leakage inductance, such a winding method is generally used in power supplies with a power of less than 30 to 40 W.
