13-level Inverter Configuration with a Reduced Auxiliary Circuit for Renewable Energy Applications

A new methodology proposes the asymmetrical multilevel inverters in which the condensers are exercised as DC-links to produce the staircase wave shape. A smaller quantity of DC sources can be used to give off the 13-level output voltage. However, the unequal DC sources are used to turn out the 13-level output. The major snag of the multilevel inverters is devices count; here, the 2 self-charging capacitors and 14 semiconductor devices are used to produce the desired output. Without auxiliary circuits, the proposed scheme created the inherent state to produce the outputs of the negative level. Lesser number of components usage desirable to use in many applications. The proposed configuration is schematized from a Back-to-Back assembly of two T type inverter and other elements. In a connection of cascaded module, it can be producing different voltage levels at higher voltages. Nearest level Control switching modulation is exercised to attain the effective sine waveform. MATLAB/Simulink platform is used to attain the simulation outcomes and a prototype module can be developed to justify the outcomes.
