This paper presents a comparative analysis between three levels neutral point clamped inverter (3L_NPC), and three levels neutral piloted point inverter (3L_NPP). Those different topologies are compared by simulation in term of many performances, as switches loss distribution which is well balanced and reduced for 3L_NPP inverter, unlike the 3L_NPC inverter. Finally, a summary of the comparative analysis is presented.

Keywords : Multilevel Inverter, 3L_NPC Inverter , 3L_NPP, Switches Loss Distrubution.
