Abstract: The invention relates to a method and a controller (8) for protection of a voltage source converter (1) comprising one or more phases (L1, L2, L3), each phase comprising one or more series- connected converter cells (2-1L1, 2-2L1,..., 2-nL1; 3-1L2, 3-2L2,..., 3-nL2 : 4-1L3, 4-2L3,..., 4-nL3). Each converter cell comprises a by-pass switch (S-1L1, S-2L1,..., S-nL1; S-1L2, S-2L2,..., S-nL2; S-1L3, S-2L3,..., S-nL3) for enabling by-pass thereof. The method comprises the steps of: detecting an over-voltage condition, and controlling simultaneously the by-pass switches of each converter cell so as to bypass the converter cells upon detection of such over- voltage condition.

Abstract: Abstract A method performed by a controller for protection of a voltage source converter comprising one or more phases, each phase comprising a plurality of series-connected converter cells , each phase being 5 connected to an electrical power grid via a respective phase reactor, each converter cell comprising a by-pass switch for enabling by-pass thereof, the method comprising the steps of: - detecting an over voltage condition, and - controlling simultaneously the by-pass switches of each converter cell so as to bypass the converter cells 10 upon detection of such over-voltage condition, wherein the voltage source converter enters a passive mode upon the converter cells being bypassed, in which passive mode the respective phase reactor of the one or more phases absorbs inductive overcurrent caused by the detected overvoltage condition. 7014964 1 (GHMailers- P95381 A[ J 1 SARAHW 19/09/2015 Sl~a S2u S3 SnL 31 3233 2n V>V-x S102 82L2 S3L2 SnL2 81 4i3.n xI S1L3 S2L30-oS3L3 SnL3" Fig. 1 x1 V>Vm..
