Thanks Bertus. Good example.In the following project the toroid coil is even bolted to the chassis, wich is the groundplane:
There are only some disks of blank PCB material as isolaton.
Had I remembered the above, my question would be superfluous. Gracias Ron.A toroid coil has very little flux (magnetic field) outside the core.
Very interesting...A toroid coil has very little flux (magnetic field) outside the core.
The toroidal transformer uses all of the windings around the same core, thus all of the flux is routed through the coils. So it is important to understand what others actually mean when they repeat things. It is also useful to be aware of how toroid transformers are constructed. And given the number in use that are working very well, it is handy to recall that seeing magnetic flux is difficult for most folks.Very interesting...
So, how in toroidal transformer almost 100% energy transfers from primary to secondary windings without 100% outer magnetic flux?
