Abstract (en)

[origin: WO2014140414A1] The invention relates to an arrangement for filtering common- mode interference. The arrangement comprises a power bridge (5, 6) connected between an AC voltage circuit (1, 4) and a DC voltage circuit (2), which power bridge comprises controllable switches (7A, 7B, 8A, 8B) for supplying electric power between the AC voltage circuit ( 1, 4) and the DC voltage circuit (2). The arrangement additionally comprises an unearthed common-mode filter circuit (9, 10, 12), which filter circuit is connected between the aforementioned AC voltage circuit (I, 4) and the aforementioned DC voltage circuit (2), in connection with the power bridge (5, 6).
