The multi-level inverter was introduced as a solution for the reduction of harmonics in the output waveform without increasing the switching frequency or decreasing the power output. The proposed multilevel converter is a cascaded connection of a three level ANPC converter and an H bridge per phase fed by photovoltaic panel. The multilevel converter is a seven-level Active Neutral-Point-Clamped (ANPC)-based and is a cascaded connection of a three-level ANPC converter and an H-bridge per phase. Depending on the switching states of converter the voltage level is maintained. The converter is operated under Space Vector Pulse Width Modulation (SVPWM) to reduce the total harmonic distortion.
