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:
- 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).
- Add option for change current working frequency.
