SEGMENTED CORE TRANSFORMER
First Claim
1. A transformer comprising a core, a primary winding and a secondary winding, the core comprising an elongate limb having a main axis, a plurality (n) of segments of a magnetic material and gaps between segments arranged in alternating relationship along the main axis, each gap having a linear segment separating extent which is parallel to the main axis, n being larger than 3, and the gaps between the segments and a gap between the core and the secondary winding being filled with an isolation medium having a dielectric strength of higher than 9 kV/mm.

Abstract
The transformer (10) comprises a core (12), a primary winding (14) and a secondary winding 16. The core prises an elongate limb (13) having a main axis (15) and comprising a plurality of segments (12.1 to 12. n) of a magnetic material and gaps (18.1 to 18.n−1) between segments arranged in alternating relationship along the main axis (15). The main axis (15) is parallel to a direction of a magnetic field in the limb (13). Each gap has a linear segment separating extent (gj which is parallel to the main axis (15). The value of n is larger than three and the gaps are filled with an isolation medium (20).
