COMPARISON OF THE 2-LEVEL AND MULTILEVEL INVERTERS:

In 2-level inverter output voltage waveform is produced by using withtwo voltage levels. This causes the output voltage and current to be distorted and the THD of the voltage is poor. In 3-level inverter output voltage and current is much more sinusoidal and the THD is better. In  2-level  inverter  the  efficiency  of  the  whole  system  is  dominated  by  the  rectifier  losses  in  light loads. In 3-level inverter the efficiency at full load is better than in 2-level inverter. This means better energy capture of the system. Better efficiency at rated power means also smaller heat sink and better reliability. Efficiency of the 3-level inverter at small power is alsoimproved. The value of P/Pmax is reduced at the knee by 50%.

Cost Comparison
In the determination of inverter configuration, usually the cost comparison of different configurationshas  to  be  executed. The cost  of  inverter  is  affected  mainly  by  the  DC-link capacitor,  IGBTand  the filtering  components,  while  the  rest  electronics  have  quite  insignificant  affectsgood  estimation  of inverter costs can be done comparing the costs of capacitor and IGBT. The impact of filtering cost can be significant.
