RT Conference Proceedings T1 A Practical Comparative Evaluation of Different Active Harmonic Filter Topologies A1 Salmerón Revuelta, Patricio A1 Pérez Litrán, Salvador A1 Sánchez Herrera, María Reyes A1 Rodríguez Vázquez, Jesús AB Along the last years, the practical use of activefilters to mitigate harmonics has been extended in electric powersystems. Different configurations of series active filters versusshunt active filters have been proposed, among them, hybridtopologies which combine active and passive filters.Nevertheless, there is not any clear accordance about the mostsuitable configuration for each type of harmonic sources. In thispaper, four different topologies of active power filters toeliminate harmonics have been analyzed. An experimentalprototype has been implemented to each configuration and havebeen submitted to different performance tests. With thisobjective, a test bank has been developed, which includesnonlinear loads kind harmonic current source, ahrmonic voltagesource, and other whose behavior is between they both. Theanalysis of experimental results obtained allows the mostsuitable active filter power topology to be determined for eachtype of load.
