A novel method for a 3-phase nine-level voltage source inverter using sixteen switch is introduced. The given technique employs conventional 3-phase bridges of two-level as a diode clamped model. A dc link voltage is supplied in such a way that the cascaded H-bridge produces the nine voltage levels. The switching patterns are stated as the levels increases then the pattern is difficult to produce three-phase outputs with fundamental modulation techniques. Here a solution for n-level inverter to produce required voltage-level with less number of power electronic components by setting up in the look-up tables. This study outlines the comparisons between nine-level voltage source inverters in different configurations and proposed novel sixteen switch three-phase inverter designed with less number of power electronic components and simulated in MATLAB/SIMULINK.
