In this paper single-phase shunt active power filter (APF) for distributed power factor correction is presented. The APF is employed to correct the power factor of groups of loads, compensating for the load current harmonic distortion as well as for the fundamental load current displacement factor. The full-bridge voltage source inverter with a three level modulation technique is used as the APF. Theoretical analysis and experimental results of a 6 kVA APF compensating for a group of loads are provided.
