Abstract

Official abstract text for this publication.

The disclosure relates to a power electronics device having at least two inverters and a transformer apparatus having a core arrangement, at least one primary winding and at least one secondary winding that wind around the core arrangement at least in sections.

First claim

Opening claim text (preview).

1 . A method for damping high-frequency components in the output current of a power electronics device having an inverter arrangement and a transformer apparatus, wherein the inverter arrangement is electrically connected to the transformer apparatus on the primary side, wherein at least two primary windings are inductively coupled to a common secondary winding in the transformer apparatus at least for a first phase, comprising, during operation of the power electronics device, temporarily applying output voltages of the same phase but with a different voltage profile to at least the two primary windings by the inverter arrangement, by virtue of the inverter arrangement being driven with clock edges that are time-shifted with respect to one another with respect to the two output voltages, such that the sum of the two output voltages corresponds to a voltage profile with a higher clock frequency than the clock frequencies of the voltage profiles of the two individual output voltages.
