چکیده
This paper presents optimal design of three-phase multilevel inverter for distributed power generation system using low frequency modulation and sinusoidal pulse width modulation as well. It is a modular type and it can be extended for extra number of output voltage levels by adding additional modular stages. The impact of the proposed topology is its proficiency to maximize the number of voltage levels using a reduced number of isolated dc voltage sources and electronic switches. Moreover, this paper proposes a significant factor which is developed to define the number of the required components per pole voltage level. A detailed comparison based on is provided. The Simulation have obtained using MATLAB software for analysis. Keyword: Low frequency modulation, multi-level inverter, multi-level inverter comparison factor, sinusoidal pulse-width modulation (SPWM), symmetrical DC power sources, three-phase.
