Abstract :
In this paper we present how the design of a power converter can be effectively improved by means of EMI phenomena simulation. We will consider the design of a converter intended as battery charger for telecommunication facilities. First of all, the phenomena involved in the generation of electromagnetic interference are reviewed. Then the main ideas used to obtain the EMI simulation model are outlined. A model of the power converter in the frequency-domain is obtained and validated through experimental measurements. Finally, this model is used to improve the design of the converter from the EMI point of view, resulting in a reduction of space, weight and cost of the filtering devices.
