Abstract
The Fourier and wavelet transform are applied to analyze the signals in a power electronics converter. The wavelet transform makes it possible to have important information about the time evolution of the frequency spectrum. Thank to this cost-processing, the source of the harmonic peaks found in the Fourier spectrum can be identified in the time evolution of the signals of the circuit under studyFile in questo prodotto:
