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.
