Zusammenfassung:	The present disclosure describes a modulation method for controlling at least two parallel-connected, multi-phase power converters. The method comprises generating synchronized switching sequences for the power converters on the basis of a common modulation reference, wherein each synchronized switching sequence comprises a first half sequence followed by a second half sequence, and wherein, for at least one of the power converters, the first half sequence is a rising-edge half sequence rising-edge half sequence and the second half sequence is a falling-edge half sequence, and, for at least one other of the power converters, the first half sequence is a falling-edge half sequence and the second half sequence is a rising-edge half sequence.
