Transformer Calculation is program for calculating number of coils and wire thickness at transformer.
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.
Note that working frequency of all calculations is 50 Hz, in next release I'll add ability to change that frequency.
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 2x7 Watts. :)

I think that you can find this program useful.
You can write to me suggestions, corrections and other things on e-mail:


Here is the list what can else I put in program:

Use this program with care!
If you allredy test and assemble transformer then that program may be very usefull.
Otherwise do not try to assemble transformer using calculations from this program!
