Influence of current sampling frequency on voltage source inverter fuzzy correction

The paper presents current sampling frequency influence on the fuzzy corrector operation in case of 3P-3W voltage source converter. The current space vector trajectory corrected for different sampling frequency was investigated. A cases of a current trajectory deformation resulting from the asymmetry of load, non-sinusoidal modulating functions and changes in the value of the input voltage were taken into consideration. Finally, the properties of the discussed cases were verified by simulation analysis.
