Analysis of multilevel inverter implementation topologies

The article presents a comparative analysis of multilevel inverter topologies, emphasizing the number of power components required for each configuration depending on the number of output voltage levels. The most popular topologies are considered, including the diode-clamped multilevel inverter, the flying capacitor inverter, the cascaded H-bridge inverter, and the level-shifted switch topology. It is shown that the level-shifted switch topology requires the minimum number of power components, which reduces implementation costs and makes the design more compact and economically efficient, especially for high voltage levels. The research results may be useful in selecting the optimal multilevel inverter configuration for power consumers that require high-quality output voltage.
