This paper deals with the development of strategies of observer and controller which allows the balancing in a close loop of the floating voltages of a multi-cellular converter. More specifically, a sliding mode control algorithm and observer is designed for the floating voltages in the multi-cellular converter. The first part of the paper deals with the importance implementation of a sliding mode...
In the modern industrial world most electronic and electrical control devices are characterized by an extreme sensitivity on power quality variations. Voltage sag is defined as a short duration reduction in voltage magnitude and is considered to be the most serious power quality issue. The accuracy limits of an index used for predicting the magnitude and duration of voltage sag caused by an increase...
