Abstract

Analyses to have a quantitative idea of the real behavior of Switching Power Supply (SPS) units from the point of view of waveform distortion and power absorption are developed. Results of several experimental tests performed by means of a test system built up at Laboratories of the Second University of Naples (Italy) are firstly reported. Then, suitable models are proposed to easily predict the behavior of SPS sets supplied by the same busbar when their number varies and these models are validated by means of accurate time domain simulations. Experimental and numerical results are discussed.
