All: I'm in the process of winding some small toroids on a T68-6 core to get about 4. the toroidal core allows efficient cooling of the copper windings. A simple transformer consists of two electrical conductors called the primary winding and the secondary winding. This illustrates why the winding's wire length on the outside of the core is wasted, mostly contributing to undesired effects. It is lacking 1,5 V AC. This is possible because core losses in toroids are typically 10% to 20% of the total power loss, with the balance being lost in the windings. Usually if the windings occupy only a short length of the available 360 degree sweep of the core, toroidal windings cannot be used. The calculation of the SMPS transformer is pretty straightforward. It has a round iron core with a coil of insulated wire wrapped around it.
