Abstract
When DC-DC converters operate in chaotic modes, they can generate spread spectra, which are useful for reducing the electromagnetic interference (EMI). Conventionally, the fast Fourier transform (FFT) is used to analyze the spectra. However, it is not applicable to the inner-harmonics, which is a prominent feature of chaotic signals. In this paper, the prony method is suggested for chaotic spectral estimation of DC-DC converters. Numerical simulations show its advantages over the traditional FFT
