Abstract
In the field of line commutated converters, for use in high voltage direct current (HVDC) power transmission, a line commutated converter comprises a plurality of converter limbs that extend between first and second DC terminals. Each converter limb includes first and second limb portions which are separated by an AC terminal. The first limb portions together define a first limb portion group and the second limb portions together define a second limb portion group. Each limb portion includes at least one switching element that is configured to turn on and conduct current when it is forward biased and it receives a turn on signal and to naturally turn off and no longer conduct current when it is reverse biased and the current flowing through it falls to zero. The converter also includes a control unit.
