On the secondary side an adaptive phase shift enables Power Factor Correction (PFC). Critical system performance includes PWM switching pattern, zero-voltage-switching (ZVS) range and switching stress for each switch are examined respectively. A novel Fast-Fourier-Transform(FFT) based modeling method...
Now, I want to calculate the phase shift between the two signals. So , I computed the peak in the FFT_magnitude and then find the phase differnce between the principal components. but unfortunately, I am not getting the expected answer. Could you please have a look, if t...
I want to do a phase shift of a signal and I can't get the right method to do it. What I am doing is that first I do the FFT of the signal and then I get Phase and Magnitude. In the phase I add or subtract the value to be shifted and then I use the new phase and the ...
