[origin: EP0024522A2] 1. An alternator for the operation of at least two discharge lamps (31, 32) comprising a stray-field transformer (12) whose core possesses a central flank (201) which carries the primary winding (2011) and outer flanks (202, 203) arranged in parallel around the central flank and, each carrying a secondary winding (2021, 2031) for the feed of a discharge lamp, there being no air gap between the central flank (201) and the outer flanks which carry the secondary windings, characterised in that the transformer core (2) consists of a ferrite core (20) of dished construction, wherein the outer flanks (202, 203) which carry the secondary windings (2021, 2031) and at least one additional outer flank (204, 204') having an air gap (2041') but no secondary winding are arranged in a circle coaxially about the central flank (201) which carries the primary winding (2011).
