Abstract—This paper presents the comparative analysis of n-level inverter. An n-level inverter has many advantages,such as reduced Total Harmonic Distortion (THD), the dv/dt is low and the EMI from the system is low, lower switching frequencies can be used and hence reduction in switching losses. In this paper the generalized n-level inverter is developed in Matlab/Simulink environment. The n-level inverters are triggered by Sinusoidal Pulse Width Modulation Technique. The 2-level, 3-level and 5-level inverter results are analyzed in terms of fundamental voltage and THD.

Index Terms—Fundamental voltage, n-level inverter, SPWM, THD
