How to setup a Stepdown Transformer in Proteus-for simulation

How to setup a Step down Transformer, with 230v primary input and 6 volt secondary output in Proteus ?



Dow does the calculation ?

 

[FvM]

L1/l2 = (v1/v2)²

 

[thannara123]

Assumed L1 is 1mH then L2 is 680mh ,Not working

 

[CataM]

Try L2=680.53 nH

 

[E-design]

If you use 1 H for the primary and 680 uH for secondary, it should be close.
1/(230/6)^2=[680.5293u]

 

[FvM]

If you use 1 H for the primary and 680 uH for secondary, it should be close.

Yes. Besides correct voltage ratio, the magnetizing inductance should be scaled appropriately. 1 H means 0.73 A magnetizing current, expectable for a 10 or 20 kW transformer.

Here is a handy calculator for coil and transformer calculations.

Thanks its correct if L1 = 1H
L2 = 680.53uH
