Reduction of Total Harmonics Distortion in PV based Three-Level Neutral Point Clamped Inverter using Space Vector Modulation

R. Kiruthiga ^[4] | S. Komalachitra

Abstract: In this paper the space vector modulation technique is applied to the three-level neutral Point Clamped (NPC) inverter, resulting to a significant reduce of ripple and total harmonics distortion. Additionally solar PV source integrated with battery storage is used as the source. Three-level neutral point clamped inverters have been widely used in medium voltage applications. This type of inverters have several advantages over standard two-level VSI, such as greater number of levels in the output voltage waveforms, less harmonic distortion in voltage and current waveforms and lower switching frequencies. This paper emphasizes the derivation of switching states using the Space Vector Pulse Width Modulation (SVPWM) technique and further reducing the total harmonic distortion. The control scheme is implemented using Matlab/Simulink. Experimentally the results are compared using the steady-state performance of the proposed control strategy.
