Abstract (en)
[origin: WO2019092014A1] A transformer (1) for use in a rail vehicle and/or for railway applications, comprising a core (2), which is surrounded at least partially by at least one coil (3, 4), is characterized with respect to the task of specifying a transformer in which the geometry of a coil can be selected as variably as possible in that the core (2) is fabricated from individual segments, wherein the overall cross-sectional area (2c) of the core (2) is greater than the sum, or equal to the sum, of the individual cross-sectional areas (2a, 2b, 2ab) of the segments, and wherein at least two individual cross-sectional areas (2a, 2b, 2ab) differ in their size and/or their geometric shape from one another and/or from the overall cross-sectional area (2c).
