Abstract (en)
[origin: WO2021249657A1] A cell (12) for a voltage source converter comprises a first cell connection terminal (CC1), a second cell connection terminal (CC2), a first series connection of two switches (T1, T2) the midpoint of which forms the first cell connection terminal (CC1), an energy storage branch (ESB) comprising a capacitor (Cc) and a crowbar branch connected in parallel with the energy storage branch (ESB), the crowbar branch comprising a first switching element (SCB1) adapted to be activated to short-circuit the capacitor (Cc) of the energy storage branch (ESB) based on the detection of a short-circuit fault and a resistive element (RD) connected in series with the first switching element and set to improve damping in the crowbar branch.
