A planar transformer and a method for the production of its winding as well as a compact an electric device with such a a planar transformer

摘要

The invention relates to a compact electrical device with a a planar transformer for the adaptation of different electrical voltages between an electrical circuit and a plug device, which can be connected with a reference voltage, wherein at least one primary winding of the transformer to the plug device and at least one secondary winding of the transformer to the electric circuit is connected via conductor tracks, the primarily - and the secondary winding surrounds at least a portion of a transformer core. Dollars a to the simplified assembly, the electronic device is a a planar transformer whose primary - and secondary winding (3a, 3b) in each case of a folded electrical conductors (15), which has a non-circular cross-section.
