Transformer Calculation v0.1 is program for calculating number of coils and wire thickness. If you have some experience in assembling transformers, then this program is perfect for you. If you don’t known anything about assembling transformers, please don’t use calculations from this program for building your own transformer! Wrong calculation can do damage to your electric device attached to electric network, and IT CAN KILL YOU !!! You can still use this program to determine how big EI core of transformer must be, if you plan to buy transformer. Note there are lot of transformers that are hybrids, so if you need transformer for amplifire buy right sized transformer. Hybrid transformer are ordinarily small and under high load it can overheat.
Current version can calculate values only for standart transformer core, that’s “W” and “U” profile of core. Toroid transformers (ring profile of core) and others aren’t supported. How I decide to write this program? Well it’s simple, I work calculation for new transformer and I didn’t have that thin wire for coil. So I lose some hours while recalculating new voltage and amperage for wire which I have. I started to assemble wire on coil and realise that wire isn’t long enough. Then I write this program and lose 3 minutes to make new calculation for that transformer with new wire. Transformer is finish and work perfect in my amplifire 2×7 Watts. :)
I think that you can find this program useful. You can write to me suggestions, corrections and other things on e-mail: email@example.com
Here is the list what can else I put in program:
Add edit option for input voltage.
Fix some bug if it’s found.
Program for recalculating if calculated wires can’t fit on coil.
Program for calculating from sqare of core, wire thickness and wire resistance characteristic of transformer (input/output voltage and amperage).

Transformer Calculation Examples
Here are some calculations what I made and from what I build transformers.
Transformer: 220V – 2x27V 8A
Input voltage 220 Volts.
Output voltage two times by 27 Volts 8 Ampers, simetric for amplifire.
EI core intersection square is 50 by 48 milimeters.
Input 220 Volts 2.258 Ampers
443 coils of 1.05 milimeters wire thickness
Here I use wire of 1 milimeter, because core is big enough and warming at that thickness is low. True reason is that I didn’t have wire of 1.05 milimeters. :)
Output 2 x 27 Volts 8 Ampers
2 x 54 coils of 1.98 milimeters round to 2 milimeters.
In assembling I use for output two wires of 2 milimeters at one quill. Begining point of two wires are joined and this is output ground, end point is two outputs of 27 Volts. I build that transformer and it works perfect.
