A power electronic converter, for use in high voltage direct current power transmission and reactive power compensation, comprises at least one converter limb including first and second terminals being connectable to a DC network and a third terminal, the or each converter limb defining first and second limb portions connected in series between the third terminal and a respective one of the first and second terminals, each limb portion including a chain-link converter, each chain-link converter including a plurality of modules connected in series, each module including at least one primary switching element connected to at least one energy storage device, each converter limb being controllable to selectively define a circulation path carrying an AC circulation current for presentation to the DC network to minimise DC ripple in a DC voltage presented to the DC network. |
