A Comparative Study of Performed SV PWM Three Phase Inverters Strategies Drive

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 inverters. This paper focuses on implementation of Space Vector Pulse Width Modulation (SVPWM) Technique for Three level Neutral Point Clamped (NPC) Multilevel Inverter and compare it with Sinusoidal Pulse Width Modulation Technique (SPWM). Simulation results were shown and compared in the view of THD for both the techniques. The result shows that the SVPWM is better for three level NPC inverter in THD point of view.
