Abstract

The invention relates to a transformer having a laminated core in the form of a frame, into whose central free space windings project which are grouped as n pairs, each composed of an inner high-voltage winding and an outer low-voltage winding located above it, around two of the opposite limbs of the laminated core, in particular for parallel operation with a plurality of supplying four-quadrant controllers. When a 16 2/3 Hz AC voltage is produced from a DC voltage by means of pulsed four-quadrant controllers, interfering current harmonics occur. In order to reduce the harmonics in a simple manner - that is to say without increasing the transformer costs, the transformer volume or the transformer weight - it is proposed according to the invention that one or more cruciform intermediate yokes (8) be inserted into the central free space (7) in the laminated core (6), which yokes divide the free space (7) into windows (9) for the individual winding pairs (1/3) in which these are inserted, and that the high-voltage windings (3) be connected in series. <IMAGE>
