Abstract
A transformer for use in a rail vehicle and/or for rail applications, including a core which is at least partially surrounded by at least one coil is, with regard to the objective of providing a transformer in which the geometry of a coil can be selected to be as variable as possible, characterized in that the core is produced from individual segments, wherein the total cross-sectional surface-area of the core is greater than or equal to the sum of the individual cross-sectional surface-areas of the segments and wherein at least two individual cross-sectional surface-areas differ from each other and/or from the total cross-sectional surface-area in terms of their size and/or geometric shape.
