TLDR
In this paper, a new multilevel inverter with reduced number of switches is proposed, which has three Dc sources and six switches and it is well suited for high power applications.Abstract:
This Multilevel inverter technology has recently become known has a very important substitute in the area of high power medium voltage energy control. Though multilevel inverter has several advantages it has drawbacks like for higher levels more number of semiconductor switches needed this may lead to huge size and cost of the inverter is very high. So in order to overcome this problem a new multilevel inverter is proposed with reduced number of switches. The proposed topology has three Dc sources and six Switches and it is well suited for high power applications. Level shifted PWM technique is used to generate the sine wave for the proposed topology. The Circuit is simulated in Matlab/Simulink and effect of harmonic spectrum is analyzed through the Fast Fourier transform window. The performance parameters of the proposed multilevel inverter are compared with the conventional MLI and another seven level existing topologies.read more
