Abstract
A transformer () comprising a primary-side auxiliary winding (, wherein in use the primary-side auxiliary winding () is configured such that a first electric potential distribution is induced in the primary-side auxiliary winding (); and a secondary-side auxiliary winding () configured such that a second electric potential distribution is induced in the secondary-side auxiliary winding (). The primary-side auxiliary winding () is physically located between (a) a main pair of windings; and (b) the second-side auxiliary winding (). A first portion of the secondary-side auxiliary winding () is positioned adjacent to a shield-portion of the primary-side auxiliary winding () such that the first electric potential distribution matches the second electric potential distribution: (1) along the respective lengths of the first portion of the secondary-side auxiliary winding () and the shield-portion of the primary-side auxiliary winding (); and (2) over a frequency range that is greater than a particular threshold frequency.
