摘要： This application describes a voltage source converter (300) of the controlled transition bridge type, having three phase limbs, each phase limb having a high side director switch (S w1 , S W3 , S W5 ) and a low side director switch (S w4 , S W6 , S W2 ) connecting a respective DC terminal (DC+, DC-) to an AC node (102a-c) for that phase limb. Chain-link circuits (101 a-c) for each phase limb comprise a plurality of series connect cells (103), each cell having an energy storage element (105) that can be selectively connected in series or bypassed. The chain-link circuits are operated in a voltage mode to provide a defined voltage transition at the AC node during a transition between one director switch being turned off and the other directors switch being turned on. In embodiments of the invention the chain-link circuits (101 a-c) are connected to a common node such that, in use, a current can flow from one phase limb to another via the respective chain-link circuits. A converter controller (900) operates a chain-link circuit of a phase limb in a current mode to provide a defined chain-link current for at least part of the time when that phase limb is not in a transition state. The defined current can allow correct circulation of the DC current and/or provide capacitor balancing of the capacitors of a chain-link circuit. Additional chain-link circuits (301, 302) are provided between the DC terminals and the common node to provide a DC current in a converter state where all the high side or low side director switches are off at the same time.
