Multi gap inductor core, multi gap inductor, transformer and corresponding manufacturing method and winding

摘要

The invention provides a multi gap inductor core, a multi gap inductor, transformer, and a corresponding manufacturing method and winding. The multi gap inductor core (1; 1'; 1"; 1"'), comprises a first plurality of magnetic lamination sheets (2a-2g; 2a'-2m'; 2a"-2n") made of magnetic core material arranged in a stack and a second pluraltity of fixing layers (3a-3f; 3a'-31'; 3a"-3l") made of a fixing material. Each fixing layer (3a-3f; 3a'-3l'; 3a"-31") is arranged between a corresponding pair of adjacent magnetic lamination sheets (2a-2g; 2a'-2m'; 2a"-2n") and includes mechanical spacer means (4; 4') which define a gap (G) having a predetermined thickness (d2) between a corresponding pair of adjacent magnetic lamination sheets (2a-2g; 2a'-2m'; 2a"-2n").
