Abstract (en)
[origin: WO2014206704A1] The invention relates to a method for controlling a plurality of multi-step converters (2), which are closed in parallel at alternating-voltage connections (21) thereof and which each have a series arrangement of two-pole sub-modules. Each of the sub-modules comprises at least two controllable electronic switches and an energy store, wherein the controllable electronic switches are connected in series forming a series arrangement and the series arrangement is connected in parallel with the energy store. In the method according to the invention, a stepped voltage curve is produced at the particular alternating-voltage connection (21) of the multi-step converters (2). The voltage curve of a second multi-step converter is offset in time in relation to the voltage curve of a first multi-step converter. The invention further relates to a converter assembly (1), which comprises means for the time delay of the alternating-voltage curve of at least one multi-step converter (2) in relation to the alternating-voltage curve of a further multi-step converter (2).
