| Abstract |
In this paper, a pulse width modulated Voltage Source Converter (VSC) connected to an AC system is investigated with respect to converter control performance for different types
of multi variable current feedback controllers. Three types of controllers are evaluated, namely a decoupling current controller with a feedforward of the line AC voltage, a Linear Quadratic state space controller and an H_ current controller. The VSC is used as an reactive power source (i.e. as a Static Var Compensator (SVC)) and the current control responses with respect to different AC network impedance are of primary interest in the analysis. |
