Abstract: Sinusoidal pulse width modulation (SPWM) and space vector pulse width modulation (SVPWM) are the most popular modulation strategies for Multi level inverters. This paper provides the theoretical analysis and simulation results of SPWM and SVPWM for three level inverter. Also this paper gives comparison between three level SVPWM & SPWM inverter. This paper concludes that SVPWM can produce about 15% higher output voltage and also it utilizes DC bus voltage more efficiently and generates less harmonic distortion when compared with SPWM technique.
Keywords: SVPWM, SPWM, THD, NPC.
