Harmonic Orientation of Multi Carrier Modulation in Neutral Point Clamped Inverter

Abstract

in this paper, a novel technique used to balancing the capacitor voltage of neutral point clamped inverter without transformer and also reduces the total harmonic distortion at the output by using multi carrier pulse width modulation technique. This paper presents orientation of higher order harmonics of fifteen level neutral point clamped inverter. The total harmonic distortion will be carried out using fast Fourier transformation. The effectiveness of the proposed method is verified by simulations.
