Universal power quality manager with a new control scheme

A new universal power quality manager is proposed. The proposal treats a nu mber of power quality problems simultaneously. The universal manager compri ses a combined series and shunt three-phase PWM controlled converters shari ng a common DC link. A control scheme based on fuzzy logic is introduced an d the general features of the design and operation processes are outlined. The performance of two configurations of the proposed power quality manager are compared in terms of a recently formulated unified power quality index . The validity and integrity of the proposed system is proved through compu ter simulated experiments.
