The possibilities of reducing conducted line emissions by modifying the basic parameters of voltage-fed pulsed inverters

Basic investigations of the influence of elementary parameters of voltage-fed pulsed inverter on conducted line emissions are presented in this paper. In addition to the variation of the DC link voltage and the output current, the effects of different dv/dt values and different operating frequencies on the inverter output are also shown. In particular, the effects of these parameters on the different frequency ranges in the noise voltage spectrum are presented. The reasons for this dependence and basic ideas for the reduction of conducted line emissions are given.
