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, the nonintegral multiples of the fundamental frequency, which is a prominent feature of chaotic signals. In this brief, the Prony method is suggested for chaotic spectral estimation of dc-dc converters. Numerical… CONTINUE READING
