Utility Multi-level inverters are increasing day-by-day in smart power system. With this their topologies are also evolving. The main challenge in designing the high-level inverters is to maintain efficiency and reliability with reduced component counts. Since as the level of output increases, requirement for the switches and other components like capacitor, diodes and sources also increases. This paper presents the cascaded type asymmetrical 19-level inverter with only 12 switches and four DC-sources. Asymmetrical topologies are the one which does not have any symmetry in the design and though the units are cascaded in structure, but they are different in topology. The proposed 19-level inverter is designed in MATLAB. |
