Abstract :

An Intelligent Controller Technique Is Used To Analyze The Performance Of A Three-phase, Fourleg Voltage-source Inverter (VSI). Reduced Current Harmonic Components And Mitigated Unbalanced And Negative Sequence Currents, Usually Caused By Single-phase Nonlinear Loads, Are Achieved Through The Integration Of A Four-leg VSI. Simulation Results Show That The Proposed Shunt Active Power Filter (APF) And Its Accompanying Control Mechanism Can Compensate In Both Steady-state And Transient Situations. Due To The Fact That An APF Is Basically A VSI That Is Controlled By Current, Intelligent Logic Controllers And PI Controllers Have Recently Found Their Way Into APF Control Applications. This Work Proposes A PI-and Intelligent Controller-based Shunt APF That Uses The Effective Time Notion To Reduce Computational Cost By Doing Away With Trigonometric Calculations. To Improve Power Quality, A Regulated Three-phase Four-leg Inverter Is Used, And The Simulation Results Show That The Shunt APF With Intelligent Controllers And PI Works. To Find Out How Effective Each Control Approach Is, We Compare The Results. Keywords: Shunt APF, LEG VSI, Power Quality, PI And AI Controllers
