Abstract: Multilevel inverters can manufacture a high- power, high- voltage inverter with a multilevel structure to control the voltage of the device. A symmetrical multilevel cascaded standard inverter requires ‘n’ DC sources for’ 2n+1′ levels that require isolated DC sources for power conversions. The objective of this paper is to increase the number of levels by reducing the number of dc sources. The proposed scheme is to use a multilevel asymmetrical inverter with a separate DC power supply. The analysis is extended to the use of the single DC power source with the remaining ‘ n-1 ‘ DC source being a capacitor and simultaneously maintains the capacitor ‘s DC voltage level and selects a fundamental frequency switching pattern to produce an almost sinusoidal output. Matlab simulink simulation is performed to verify the performance of the Asymmetrical Multilevel Inverter using isolated Dc source. The results of simulation and hardware are presented and discussed in this paper.
