1. Thyristor valve for high voltage power convertors with a plurality of series-connected thyristors (T) and with voltage dividers (C1, R1, ZD) connected in parallel with said thyristors, whereby the thyristors are provided with capacitors (C2) being charged from taps on the voltage dividers, which capacitors (C2) serve to supply the control devices (SD) of the thyristors, characterised in that each capacitor (C2) is connected in series with a resistor (R2), and that this series connection is connected to the voltage divider as well as to the supply input (S) of the control device (SD). |
