ANALYSIS OF QUALITY SENSITIVITY OF THE OUTPUT CURVE OF AN INVERTER VS. ACCURACY OF ITS PARAMETERS
The paper describes a method for analyzing sensitivity of quality parameters of the electric energy generated by a multi-level voltage inverter in relation to the fuzziness of the parameters of its curve. The given technique is based on the use of fuzzy numbers, the principle of Zadeh generalization, and idea of fuzzy sensitivity. The results of fuzzy sensitivity estimates of the harmonic distortion factor in the output curve of a multi-level inverter to fuzziness in setting switching times and value of its levels are presented.
