Abstract (en)
[origin: WO2016082944A1] The transformer of the invention comprises a first coil that has three or four windings, preferably exactly three windings, a second coil, and a U-shaped core. The length of the transformer is 40 mm or less, resulting in a compact volume, for example for ignition units of luminaires, and production costs are reduced because a U-shaped core is used.
