Modelling and simulation of single phase simplified eleven-level inverter

Abstract

This paper presents modeling and simulation of a single phase simplified eleven-level inverter (SELI). Multilevel inverter offers high power capability. Its performance is highly superior to that of conventional two-level inverter due to reduced harmonic distortion, lower electromagnetic interference and higher dc link voltage. The inverter is capable of producing eleven levels of output voltages (Vdc, 4Vdc/5,3vdc/5,2Vdc/5, Vdc/5, 0,-Vdc/5,-2Vdc/5, -3Vdc/5,-4Vdc/5,-Vdc) from the DC supply voltage. Theoretical predictions are validated using MATLAB Simulink tool box.
