However, the theoretical analyses as well as experimental results have indicated that ostensible reduction of the EMI level generated by random modulated converters results from the methodology of the EMI spectrum measurement, adopted in currently binding standards, rather than physical nature of interference generation phenomenon. The experimental investigations, presented in the paper, have shown that utilization of commonly used EMI measuring standards might lead to wrong conclusions in a case of assessment of electromagnetic compatibility of random modulated converters. The aim of this paper is to propose the novel, efficient method enabling objective evaluation of the EMI generated by random modulated converters.
