OPTIMIZATION OF SWITCHING ANGLES FOR SELECTIVE HARMONIC ELIMINATION IN CASCADED H-BRIDGE MULTILEVEL INVERTERS EMPLOYING ARTIFICIAL INTELLIGENCE TECHNIQUES – A MINI REVIEW

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