Abstract :
Wavelet transformation based on m filters for multi-scale analysis is considered. Modeling the three-phase grid-controlled inverter is carried out and time function of load inductance current for different inductance are received. Wavelet-spectrum for these functions are constructed and the influence of the converter parameters on wavelet coefficients is investigated.
