Use of multisine excitations for frequency-response measurement of nonlinear DC-DC switching converters

摘要

In this paper, the application of multisine signals to the frequency-response measurement of switching converters is addressed. It makes some considerations on the available parameters of the signal and its influence on the measurement. The experimental set-up, where a boost converter is considered due to its well known non-linear effects, is described. Additionally, several experimental results are provided to illustrate all the concepts involved.
