Abstract :
Electromagnetic interference (EMI) is usually difficult to predict and the interference problems may dramatically lengthen the time-to-market of a new power supply product. The possibility of predicting the EMI-spectrum from the switching function of a switching power supply by means of simulation is analyzed in this paper. Simulated spectra are compared to the measurements made with a spread-spectrum DC-DC converter
