  "textContent": "The present disclosure relates to an electronic valve apparatus for a high voltage direct current, HVDC, power transmission system. The electronic valve apparatus comprises a first device chain () including a plurality of first devices () connected in series between an input node () and an output node () of the electronic valve apparatus (). Each of the plurality of first devices () has an asymmetric transfer function configured substantially to block current flow through the device in a first direction, and the plurality of first devices () are connected such that they all block current flow in the same direction. The electronic valve apparatus also includes a second device chain () including a plurality of second devices () connected in series between the input node () and the output node (). Each of the plurality of second devices () has an asymmetric transfer function configured substantially to block current flow through the device in a first direction, and the plurality of second devices () are connected such that they all block current flow in the same direction. The second device chain () is connected in parallel with the first device chain ().",
