Abstract (en)
[origin: WO2016083866A1] The invention relates to a basic module of a magnetic core of a wound electrical transformer. Said basic module is characterized in that it consists of a first (1, 2) and second (3, 4) winding that are placed one on top of the other and made of a first and second material, respectively. Said first material is a crystal material having a saturation magnetization (Js) greater than or equal to 1.5 T and magnetic losses less than 20 W/kg in sine waves having a frequency of 400 Hz, for maximum induction of 1 T, and said second material is a material having an apparent saturation magnetostriction (λsat) less than or equal to 5 ppm and magnetic losses less than 20 W/kg in sine waves having a frequency of 400 Hz, for maximum induction of 1 T. The cross-sections (S1, S2) of the first winding (1, 2) and cross-sections (S3, S4) of the second winding (3, 4) are such that the proportion (S1/(S1 + S3); S2/(S2 + S4)) of the first material, having a high saturation magnetization (Js), compared to the cross-section of both materials together, is between 2% and 50%, preferably between 4% and 40%. The invention also relates to a magnetic core of an electrical transformer, comprising at least one such basic module, to a method for manufacturing said magnetic core, and to a transformer comprising said magnetic core.
