Short duration voltage disturbances like voltage sags are receiving much attention, since they are very common. Voltage sags are characterized by short duration; nevertheless they can result in the shut down of an industrial process or in the maloperation of the control system of devices like AC-DC converters. In this paper, a fast controller...

Voltage sags are very frequent events associated with faults in the network, with energization of transformers or starting of large motors. Although their duration is very short, they can represent a big problem for industrial plants, especially for those characterized by the presence of sensitive loads, like power electronics devices. In this...
