A modified diode clamped inverter with reduced number of switches

This paper presents a novel multilevel inverter with reduced number of switches based on a modification to conventional diode clamped inverter. Diode clamped inverter is a well-known and wide-spread multilevel inverter among other inverters. Therefore, it has been modified in this paper to use fewer number of components to generate the same output voltage levels. This modification makes the proposed topology an excellent choice for low to medium power industrial applications. Moreover, the circuit operation is analyzed with MATLAB/Simulink for a nine level topology to show the performance of the circuit. A comparison between different topologies based on the number of components is carried out to clarify the advantages of the proposed topology over other ones.
