In authors proposed a new three-phase multilevel inverter with single DC source. Design involves combination of cascaded H-bridges and standard two level inverter, this arrangement is shown in Fig. 15 (c). The proposed configuration generates multilevel output voltage with very less number of switching components.
In this work, two new topologies of single-phase hybrid multilevel inverters for symmetrical and asymmetrical configurations are presented for use in drives and control of electrical machines and the connection of renewable energy sources.
The proposed configuration generates multilevel output voltage with very less number of switching components. Author verified the proposed version with a 19-level three phase inverter. For verification of 19-level inverter, author utilized four H-bridges and one standard inverter.
Fig. 1 shows the proposed topology for symmetric multilevel inverter. As the figure shows, the multilevel inverter is composed of two parts: the level creator part and the H-bridge. The level creator part generates the voltage levels using a specific arrangement of dc sources and power electronic switches.
In the literature, various topologies have been reported for providing a large number of output voltage levels without increasing the number of bridges; these topologies are called asymmetrical multilevel inverters whose magnitude of DC voltage sources is unequal.
