Abstract
This paper presents a transformerless topology of series active power filter with capability to
protect sensitive loads against harmonics, sags, swells and unbalances of the power system
voltages. The proposed topology is constituted by three isolated H-bridge with a voltage source
at the DC side. The series active power filter has been studied with the help of PSIM (Power
Simulation software) and simulation results are presented. A laboratory prototype is under
development and experimental results are shown.Fundação para a Ciência e a Tecnologia (FCT) - PTDC/EEA-EEL/104569/200
