Abstract

A terminal model is a common method to create equivalent models of DC-DC converters in order to predict conducted emissions. In this paper, a characterization method for converters with stochastic behavior is presented. The averaged and maximized spectra of the measured voltages and currents are used to create the model. The phase information is obtained using a dedicated reference channel. After the equivalent source was determined, the actual induced noise voltage at the test load was compared to that predicted by the model with the averaged and maximized spectra to estimate its accuracy. The results indicate that the agreement with the direct measurement is between 10 dB and 100 MHz.
