Abstract
The research project deals with three-phase pulse converters, that can be applied in measurements and electrical drives. Previously, the research team has successfully resolved the problem of converter''s output voltage active filtering. The converter thus generates sinusoidal voltage, which has several advantages when compared to current output, e.g. better EMC and improved efficiency. Measurement applications require special solutions considering purity of output voltage, where strict limits of harmonic distortion and DC offset must be complied. Appropriate modifications in the control loop and in triggering of the solid-state power switches were implemented to meet the requirements. But optimizing the elements of the active filter and finding the optimal switching frequency of the power stage still remain the matter of further research interest.
