Figure 9-5 shows the phase current waveform when dead time compensation is disabled. Fundamental frequency of phase current is 40 Hz. Fast Fourier transform (FFT) of phase current plot shows harmonics at 160 Hz and 220 Hz. Figure 9-6 shows the phase current waveform when dead time compensation is enabled. Phase current looks more sinusoidal and the FFT of phase current plot does not have any harmonics.
