RE: [TCML] Torroid/Shorted Turn?

["Lau, Gary" <Gary.Lau@xxxxxx>]

If you search the Pupman.com archives for "toroid shorted turn" it's been discussed many times.  The consensus is that the toroid is too far away from the primary and its high currents & magnetic fields, for losses to be significant.
