Abstract

Non-linear loads, such as diode and thyristor converters, saturated transformers and arc furnaces are typical sources of harmonic currents. Current harmonics have direct and indirect harmful effects on the components connected to the same power supply with harmonic source and on the surrounding device via electric and magnetic fields. Therefore current harmonics must be filtered. The harmonic currents can be filtered using either parallel-connected passive or active power filter or series hybrid active power filter (SHAPF). The filtering performance of active and hybrid filters is strongly affected by the DC-link voltage of the converter included in these filters. In this paper, this influence of the DC-link voltage control on the harmonic compensation result of two SHAPFs is investigated. Research is verified by experimental tests with SHAPF prototypes
