Abstract:
1. A converter device for converting an electrical input power to an electrical output power, the converter device comprising: a voltage input for receiving a voltage signal, said voltage signal being indicative of a voltage in an electricity network to which the converter device is coupled during operation in order to provide said electrical output power to said electricity network; a controller being configured for setting a reactive component of said electrical output power depending on said voltage signal according to a predetermined out-of-band reactive current gradient if the voltage indicated by the voltage signal is outside a predetermined voltage band, thereby varying the reactive component so as to vary a reactive current according to the predetermined out-of-band reactive current gradient; wherein the predetermined out-of-band reactive current gradient is defined as change of reactive current per voltage unit of a change in the voltage indicated by the voltage signal, wherein the predetermined voltage band is set to a width which varies as a percentage of a rated value of the voltage signal.
