Considering present shortage of fossil fuels and discharges of ozone harming substances, power developed from Renewable Energy Sources (RES) is identified as the excellent choice for producing the electricity. The characteristic of an inverter is to transform the dc power into ac power to fulfill out the requirements of load. Despite its advantage, the presence of harmonics in the output voltage reduces both the efficiency and the performance of the inverter. Several researches have been carried out since last three decades for eliminating the harmonics. Based upon several researches, it reveals that the Selective Harmonic Elimination Pulse-width Elimination technique (SHEPWM) has proven to be the best in eliminating lower order harmonics. But when calculus based methods are used for solving the non-linear transcendental equations, this technique has shown some complications. Artificial Intelligence (AI) techniques appear to be better in solving the above said equations. This review paper provides the performance of some AI techniques used for eliminating the harmonics in inverters. Based upon the information collected from various literatures and its results, conclusion has been made.

The Seven Step multilevel inverter has 3 H – Bridge switching circuits which are designed from transistor and IGBT semiconductor circuits. The performance of the switches is regulated by the ignition unit which consists of pulses of frequency with a certain ignition angle. This pulse pulse determines the output voltage form of the H-Bridge multilevel inverter circuit. The output voltage form is a square pulse. There are seven step output voltage levels that are close to a sinusoidal shape, but still contain high levels of harmonics. This large Total Harmonic Distortion (THD) can be overcome by increasing the number of levels or steps in the output voltage by adding an H-Bridge strand to the next level. The modeling of this 7 step multilevel inverter circuit is designed using Matlab Simulink Tools.

: A wide spread use of fossil fuel has lead to extreme increment of carbon footprint in the world globally. Earth’s melting glaciers are informing us to go for renewable energy sources. In most cases, the renewable power has been generated in electrical form and the same does not suit the existing grid requirements. Cascaded H bridge multilevel inverters Topology is promising in this context. The output of multilevel inverter is near to sinusoidal and has added advantages of low device stress, no need of step up transformers, low common mode voltage, near sinusoidal input current, low switching frequency and reduced harmonics. The direct output of Cascaded H bridge multilevel inverters may not be suitable for many applications like integrating solar panel output with existing grid where harmonic reduction is necessary. Various modulation techniques are available like sinusoidal pulse width modulation, space vector modulation and selective harmonic elimination. Among the listed modulation techniques, selective harmonic elimination can be implemented with low switching frequency and it is suitable where low electromagnetic interference, low switching loss and good power quality is required. To reduce the harmonics one must solve the non-linear transcendental output equations of the cascaded H-bridge Multi level inverter (CHB-MLI). Various artificial intelligent (AI) algorithms are introduced and researchers have worked on eliminating harmonics or minimizing total harmonics distortion (THD) from the output of CHB-MLI. This paper gives review of the harmonic reduction using some of the well known explored AI algorithms and also gives insight to some of unexplored algorithms in this area.
