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.

摘要： A voltage source converter (VSC) has one or more switching modules that may form a director switch of a converter arm of the VSC. A power distribution system 200 of the VSC has a power distribution loop 201 and one or more power distribution modules 205 that provide power from the power distribution loop to the switching module(s). A set of one or more floating power supply modules 202 generate an AC current in the power distribution loop. The floating power module(s) derive power from a voltage across one or more components of the VSC (e.g. an energy storage component or one or more semiconductor switches) and are not ground referenced power supplies, avoiding problems of suitable isolation. A ground referenced supply 207 may be removably connected to the power distribution loop to provide power when the VSC is not energised. A power controller may operate in: a single supply mode, to selectively activate a single floating power module with the other floating power modules inactive; or a multiple supply mode, where the power controller selectively activates more than one of the floating power modules. At least one of the floating power modules may be connected in series with, or inductively coupled to, the power distribution loop when active.

摘要： This application describes methods and apparatus for achieving voltage balancing of clamp capacitors of director switch units of a voltage source converter (VSC). An arm or director switch (104) may be formed from a number of director switch units (200) connected in series, each director switch unit having a semiconductor switching element (110) such as an IGBT. Typically a clamp capacitor (202) may be connected across the IGBT. In some arrangements a floating power supply (208) may draw power from the clamp capacitor (202) to provide power for the director switch unit (200). In the present application the director switch unit (200) is operable in a voltage balancing mode such that the power drawn from the clamp capacitor varies based on the voltage across the clamp capacitor. In this way the power demand for power drawn from the clamp capacitor may have the characteristic of a resistive load.
摘要翻译：本申请描述了用于实现电压源转换器（VSC）的控制器开关单元的钳位电容器的电压平衡的方法和装置。臂或导向器开关（104）可以由多个串联连接的导向器开关单元（200）形成，每个导向器开关单元具有诸如IGBT的半导体开关元件（110）。典型地，钳位电容器（202）可以连接在IGBT两端。在一些布置中，浮动电源（208）可以从钳位电容器（202）汲取电力以向导向器切换单元（200）提供电力。在本申请中，导向器开关单元（200）可在电压平衡模式下操作，使得从钳位电容器汲取的功率基于钳位电容器两端的电压而变化。以这种方式，从钳位电容器汲取的功率的功率需求可能具有电阻负载的特性。
