Abstract (en)

[origin: EP1085537A2] Planar transformers with compact electronics arranged in shock-proof mounting and particularly suitable for use in motor vehicles, have the primary and secondary windings (3a,3b) each designed as a folded electrical conductor (15) having a non-round cross-section. These electrical conductors (15) are formed from a metal strip or band, or as a sheet-metal part and at least one insulation layer is arranged parallel to the electrical conductor (15) and can be folded with the electrical conductor (15) in one working step.
