Abstract

The invention refers to an inverter (3) for an electric machine (1), comprising at least two parallelly connected power units (6, 8) each configured to provide a multiphase AC output (7, 9) to stator windings (4, 5) of the electric machine (1) and a control unit (13) configured to provide a set of pulse sequences to each power unit (6, 8), wherein the phase positions of the sets of pulse signals are interleaved to each other, wherein the control unit (13) is configured to vary a pulsing frequency of the sets of pulse sequences and to adjust the mutual phase position of each set of pulse sequences to the interleaved phase positions when varying the pulsing frequency.
