This paper deals with the estimation of systematic and random contributions that could influence the measurements of conducted emissions by adjustable speed electrical power drive systems. Beside the uncertainty due to the measurement chain, the EMC test arrangement was considered as a possible source of uncertainty since it could compromise the result reliability and the compliance/non-compliance of a given apparatus. In order to completely identify all the uncertainty components, test were carried out varying some influencing configuration parameters. Their effects on the measurement results were evaluated for the most common inverter modulation tecniques. The measurement reproducibility evaluation completes the analysis carried out.

Abstract

This paper deals with the estimation of systematic and random contributions that could influence the measurements of conducted emissions by adjustable speed electrical power drive systems. Beside the uncertainty due to the measurement chain, the EMC test arrangement was considered as a possible source of uncertainty since it could compromise the result reliability and the compliance/non-compliance of a given apparatus. In order to completely identify all the uncertainty components, test were carried out varying some influencing configuration parameters. Their effects on the measurement results were evaluated for the most common inverter modulation tecniques. The measurement reproducibility evaluation completes the analysis carried out.
