In this manuscript, a new seven-level (7-L) inverter circuit by means of a solitary dc basis, capacitors and switching devices is promoted. This topology employs only a single independent dc source, three dc capacitors, two diodes and seven switching devices. All the elements in the system are effectively utilized to generate the required the voltage level of output. This topological approach has higher reliability and lowers the harmonic distortion due to the fewer the system contains a lot of components and due to the production of a higher sum of stages in the output. The dc capacitors have the advantage of natural voltage balancing due to symmetric production voltage stages in this topology. The operating modes and Detailed description of the modulation method of the suggested structure. In the SIMULINK/MATLAB environment, the proposed network topology is also simulated with the results.
