A power conversion system including: a first self-commutated converter connected between a first AC power system, and a first DC main line and a DC return line for first high voltage DC transmission; a second self-commutated converter connected between the...

In the field of chain-link modules for voltage source converters, there is a need for an improved chain-link module. A chain-link module, for connection in series with other chain-link modules to form a chain-link converter selectively operable to provide ...
