Abstract (en)
[origin: WO2020114653A1] The invention relates to a circuit device (100) for reducing common-mode interference of a power converter (60), the power converter (60) forming a common-mode interference source during operation. The circuit device (100) comprises at least one short-circuited additional line (50), which can be coupled to an input (10, 15) and an output (20, 25, 30) of the power converter (60). The additional line (50) conducts the interference currents produced by the common-mode interference source and returns said interference currents to the common-mode interference source.
