Abstract (en)
[origin: GB2307795A] An isolation transformer comprises two or more independent magnetic paths formed by high permeability magnetic cores 7, 8. Each magnetic core 7, 8 includes one or more independent windings 1, 4 and at least one coupling winding 6. Each core 7, 8 and its independent associated winding(s) 1, 4 is enclosed by an electrostatic screen 2, 5 whilst the coupling winding 6 is located outside the electrostatic screen 2, 5. The coupling winding 6 may be formed by interconnecting separate windings associated with individual cores and may be arranged to couple with more than two cores. Alternatively a core with a primary winding may be linked by plural coupling windings to respective secondary cores to drive plural secondary output windings.
