Copper wire for high frequency converters
Designers use Litz copper wire for high frequency windings. That rapidly increases the diameter of wire needed and decreases the stacking factor.
Should’t it be possible to make a copper wire with ...

Transformer copper loss
In this Example the efficiency for a full-load transformer was asked to solve. The book calculated the copper losses after referral to the secondary side as the following : Pcu = (Is)^2Req = (65.2 A)^...

Why is the magnetic field not blocked by the copper wires in a current transformer?
When I want to protect an electronic board from a magnetic field generated by a transformer, I put a circle of vias (as a jail grid) connected to GND planes to stop the magnetic field.
How does a ...

Using distribution transformers vs direct connection to primary switch gear
I am trying to learn more about transformers and low voltage electrical distribution.
Say you have a medium sized industrial building with a primary switchboard feeding several load centers ...
