Survey of Active Power Filters Configurations

The rapid growth in nonlinear appliances over the past years has increased the power quality problems along the grid. This has called up a continuous research to develop the active power filters. The persistent development has produced numerous applications that have helped in improving the power quality. Although many publications were dedicated to reviewing active power filters, this survey organizes and evaluates the existing reviews to identify the patterns and the new trends in this field. This paper seeks to assemble the existing approaches concerning different aspects of active power filters and their control techniques. This review should be quite beneficial for engineers and researchers who are interested in solving power quality issues using active filters to be able to select the most adequate and preferable technique for their applications.
