In the field of High Voltage Direct Current (HVDC) power transmission there is a need for an improved control module. A control module (40), for controlling a chain-link component (26, 28) of a converter (10), comprises two controllers (42, 44). Each controller (42, 44) is configured to selectively control a chain-link component (26, 28) in accordance with a control program that is stored in the said controller (42, 44). The control module (40) is configured to replace the control program stored in one of the controllers (42, 44) with a replacement control program while the other of the controllers (42, 44) is controlling the chain-link component (26, 28). |
