Experimental Investigations of a Three-Phase Active Filter for the Use in Modern Electronic Power Converters

摘要

Results of experimental investigations of a three-phase active filter are presented. The filter is implemented on a basis of a mass-produced Universal frequency converter. The results of the investigations enabled a conclusion to be made that, for the frequency converters of this type to be used in reversible energy conserving electrical drives, it is sufficient simply to duplicate their inverter part with the appropriate adaptation of their hardware and software controls.
