In the industry, multilevel inverters are preferred for its application in high voltage and power. With this increase in the voltage level, the inverter's output gets better with fewer harmonic distortions. Multilevel inverters are usually used in a high-power system. As such, when there is an increase in the level of voltage, there is complexity added to the power circuit also. For resolving the challenge a unified PWM method through space vector modulation is devised for a dual 2-level 5-phase inverter system. The study is a research of all aspects of the dual 2-L 5-phase VSI, which deals with power circuit diagram using an open-end winding, the generation of vector with the appearance of the reference vector in all three regions, the time distribution of voltage vectors, the plane of voltage vector, the voltage selection for the two inverters, and the switching sequence of the two inverters in all three regions. To validate the obtained results, MATLAB/SIMULINK models based on the SVPWM scheme are developed. The output of the dual 2-level inverter system is analyzed in terms of fundamental voltage and total harmonic distortion. Finally, the output is investigated for different isolated DC sources present in both the inverters. The findings have been presented in terms of the fundamental voltage and percentage THD.
