Abstract— In this paper, different sinusoidal pulse width modulation (SPWM) control strategies of multilevel flying capacitor inverter are presented. Three control strategies are studied; the triangular multicarrier SPWM, the saw tooth multicarrier SPWM and the sinusoidal multicarrier SPWM. This work begins with a presentation of the flying capacitor inverter. Then a paragraph that gives a brief review of the triangular multicarrier SPWM, the saw tooth multicarrier SPWM and the sinusoidal multicarrier SPWM. A comparison between the three SPWM control strategies is established based on the simulation results. The comparison objects are the root mean square rms of the output voltage and the total harmonic distortion (THD). The results obtained demonstrate that the sinusoidal multicarrier SPWM is better than the saw tooth multicarrier SPWM and the triangular multicarrier SPWM. Simulations are carried out by PSIM program.
