In this study, an advanced configuration for symmetric multilevel voltage source converters is
proposed, which is well-designed in order to provide the maximum number of voltage levels in output
terminals using reduced number of circuit devices. The overall cost and size of multilevel inverters depend on
the number of devices used in the circuit, such as power switches, gate driver circuits and DC voltage sources.
Furthermore, for a circuit with reduced number of devices, the control scheme will be simpler and reliability
will be enhanced. The comparison among the proposed inverter and recently reported inverters in literatures,
is provided in this paper. It is shown that the suggested inverter has reduced number of circuit equipment,
which in its turn reduces the total cost. The suggested configuration is modeled and simulated by
MATLAB/SIMULINK software and compared with the experimental results of the proposed topology
prototype to indicate its well-performance.
