Analyzing Frequency Spectra of Signals Generated by Chaotic DC–DC Converter and Its Application in Secure Communication
In this paper, a hybrid Adaline-Prony-based frequency estimation technique has been developed. Using this technique, the spectral estimation of the signals generated by current mode controlled buck–boost converter operating in chaotic condition is done. From the results obtained, it is shown that the signals generated by buck–boost converter in chaotic condition possess spread spectrum characteristic. Based on the results, a new vista of research can be opened in designing spread spectrum secure communication model using chaotic DC–DC buck–boost converter. To the best of our knowledge, very few researchers have given a thought in direction of using chaotic DC–DC power electronics converters in secure communication.
