Abstract (en)
[origin: WO0223705A1] The invention relates to a filter circuit configuration for a single-phase or three-phase converter circuit (7) for limiting the steepness of the switching voltage of the converter circuit (7) when changing potential. Said filter circuit configuration comprises at least one inductor (2) located at alternating current connections (1) of the converter circuit (7). An electrical load (6) and a voltage-limiting device (4) are connected to each inductor connection (3) provided at the inductor (2), and a filter capacitor (5) is provided between each of the inductor connections (3). In addition, the inductor (2) and the filter capacitor (5) in the filter circuit configuration are selected in such a manner that the resonance frequency (f>res<) of the filter circuit configuration is significantly greater than the switching frequency (f>s<) of the power semiconductor switch of the converter circuit (7).
