| Abstract |
Along the last years, the practical use of active filters to mitigate harmonics has been extended in electric power systems. Different configurations of series active filters versus shunt active filters have been proposed, among them, hybrid topologies which combine active and passive filters. Nevertheless, there is not any clear accordance about the most suitable
configuration for each type of harmonic sources. In this paper, four different topologies of active power filters to eliminate harmonics have been analyzed. It has been implemented an experimental prototype corresponding to each configurations more used and they have been submitted to different performance tests. With this objective, a test bank has been developed, which includes voltage-source nonlinear loads, current-source nonlinear loads, and other whose behavior is between both. The analysis of experimental results obtained allows the most suitable active filter power topology to be determined for each type of load. |
