ANALISE E IDENTIFICACAO DE FALTA NO COMANDO DE INTERRUPTORES DE CONVERSORES USANDO WAVELET

Résumé

Wavelet Transform (WT) has been attracting interest in applications of the electric signs analysis, in contrast with the methodology classic for determination of the spectrum signs during transient or no stationary signs that use Short Time Fourier Transform (STFT). This new mathematical tool it shows e±cient and fast. In this work is presented an identi¯cation methodology and diagnosis of intermittent operation °aw of the static converter command using a function wavelet mother mexican hat. Identi¯cation and diagnosis are accomplished starting from the current analysis of the converter output current that feeds the induction motor. Simulations and experimental results are presented for investigation and validation of the methodology proposed.
