Abstract (en)
[origin: WO2021174281A1] The invention relates to a converter assembly comprising a direct voltage link (1) for providing direct voltage VDC, comprising a positive terminal and a negative terminal, and at least one machine converter (2) for converting the direct voltage VDC into a multi-phase alternating voltage, wherein at least one energy storage capacitor (3, 3') is located in the direct voltage link (1), and a frequency-dependent resistor (4) having a higher electrical resistance at high frequencies than at low frequencies being connected in series with the energy storage capacitor (3, 3').
