Abstract

The converters (1, 2, 3) having a single-phase AC-voltage output each have a linearising drive unit (7, 8, 9) and, on the output side, are connected in an m-phase star circuit to an m-phase balanced, star-connected load (6), precluding a direct connection between the star point (Mu) of the m converters (1, 2, 3) and the star point (MM) of this load (6). The conductor voltages on the load together form a balanced system. In order to increase the power transmitted from the converters to the load (6) it is provided that the drive unit (9) of at least one of the m converters (1, 2, 3) be provided upstream with a control voltage (Us3) in such a manner that the output voltage (U3) of this said converter (3) has an essentially trapuzoidal waveform which, in addition to a fundamental, also contains at least one harmonic of an odd-numbered order which can be divided by m. Direct converters, in particular, can be provided as the converters (1, 2, 3). The circuit arrangement is preferably suitable for supplying a rotating-field machine. <IMAGE>
