Combined Modulation and Harmonic Suppression
2006 CES/IEEE 5th International Power Electronics and Motion Control Conference, 2006 The output of pulse width modulation includes harmonics with invariable frequencies and invariable magnitudes, which are sources of conducted interference and load resonance. Based on the spectrum analysis of switching modulation and sinusoidal pulse width modulation (SPWM), frequency modulation and low frequency amplitude modulation are combined to ...
