Abstract

The invention relates to an inverter comprising at least one inverter bridge (4), a DC reactor connected upstream of the inverter bridge (4) for rejecting common-mode interferences on DC lines of the inverter, and an AC reactor connected downstream of the inverter bridge (4) for rejecting common-mode interferences on AC lines of the inverter; the DC reactor includes at least two magnetically coupled DC windings (101, 102) which are each connected upstream of a DC terminal of the inverter bridge (4), and the AC reactor includes at least two magnetically coupled AC windings (104, 105) which are each connected downstream of an AC output of the inverter bridge (4). The inverter of the invention is characterized in that the at least two DC windings (101, 102) and the at least two AC windings (104, 105) are magnetically coupled to each other. The invention further relates to a reactor (100) for rejecting common-mode interferences in a power converter.
