摘要： This application relates to a voltage source converter, especially for use in High Voltage Direct Current power distribution/transmission, and to methods of control of such a voltage source converter. The voltage source converter has at least one phase limb having a high-side DC terminal, a low-side DC terminal and an AC terminal. In embodiments of the invention each phase limb comprises a voltage wave-shaper operable, in use, to provide a selectively variable voltage level. Each phase limb also has a switch arrangement operable to provide at least first and second switch states. In the first switch state the low-side DC terminal is electrically connected to the AC terminal via a first path that includes the voltage wave-shaper. In the second switch state the high-side DC terminal is electrically connected to the AC terminal via a second path that includes the voltage wave-shaper.
