Efficiency Improvement in Novel Multilevel Inverter Topology using Modulation Technique (Level and Phase Shift) by Reducing Switching Losses

to examine the effectiveness of applying PWM (Pulse Width Modulation) approaches to reduce switching losses in innovative multilevel inverters. In innovative multilayer inverters, switching loss is controlled by using level shift and phase shift approaches to boost efficiency for variable DC input voltage. Sample size is calculated using Gpower and found to be totally 40 samples. Based on the results obtained, phase shift (83.3%) has more efficiency when compared to Level shift (78.2%). Phase shift provides better efficiency when compared to level shift for different input data sets.
