A technique for the reduction of harmonic distortion and power losses in advanced static VAr compensators

The harmonic reduction technique presented is suitable for the application to advanced static VAr compensators (ASVC). The technique is combined with a soft switching strategy to reduce the low order harmonics and the switching losses. The theoretical basis is established and the effectiveness of the method is investigated by simulation and experiment. Both hard switched and soft switched ASVCs are considered. Theoretical and experimental results show good agreement.<
