Development of Novel Multilevel Inverter with Reduced Power Switches

In recent days the usage of multilevel inverters became very essential and crucial
especially on high power consuming sites. The advantages on the modularity, failure
management, reliability and the waveform with less harmonic distortion at the output
made the multilevel inverter to gain more attention in the current industry. Even
though, multilevel inverters serving the industry with more significant advantages
however they do have drawbacks such the usage of high number of power switches
in their circuit and this leads to high manufacturing cost and also increase the
complexity of the circuit structure. In this paper a new 9 level multilevel inverter
topology has been analyzed. The proposed topology has considered factors such as
reducing the power switches, reducing the total harmonic distortion and reducing the
complexity of the structure.
