Multilevel inverters are gaining popularity in renewable energy applications today. This paper presents the configuration of a three level and five level Neutral Point Clamped inverter. Phase Disposition Sinusoidal Pulse Width Modulation strategy is employed to generate switching pulses for both the multilevel inverters. Using the modulation technique, the output voltage, output current and harmonic spectrum of both the inverters are obtained. Further, this work presents the design of a passive LC filter to reduce harmonic distortions from the multilevel inverter output. The performance of the designed filter is studied by analyzing the output waveforms and the harmonic spectrum obtained after connecting the designed filter to the inverter output. All the simulations are carried out in MATLAB-Simulink simulation platform. It is found that the designed filter keeps the output harmonics within IEEE standards. © International Science Press.
