چکیده
Multilevel inverter technology has emerged recently as a very important alternative in the area of high-power medium-voltage energy control. This paper presents modeling and simulation of a single phase simplified eleven-level inverter (SELl). 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. Recent advances in technology have realized the cascaded inverters with separate DC sources to have a considerable reduction in switching losses and the ability to control the harmonic content.The elementary concept of a multilevel converter to achieve higher power to use a series of power semiconductor switches with several lower voltage dc source to perform the power conversion by synthesizing a staircase voltage waveform.Simulations of eleven level of the proposed inverter topology along with MATALAB simulation results are presented.
