Harmonic Reduction in Inverter with Different Techniques Including Fuzzy Logic Controller

Anupriya Jain | Shobhna Jain

Abstract: In recent years, the growing and widespread use of power electronic equipments by totally different segment of society is perceptible. But, these equipments present itself as nonlinear impedances in power system and generate harmonics with well-known adverse effects such as low power factor, electromagnetic interference, voltage variations resulting in flicker, etc resulting higher THD values. In the proposed paper, a comparative analysis of voltage T. H. D. has been carried out for Sine PWM inverter without filter, SPWM inverter with LC filter, fuzzy logic controlled SPWM inverter. An attempt is made to identify a control technique which permits higher harmonic reduction within the AC output voltage of the inverter. The realization and analysis of inverter circuits and various control techniques is done using MATLAB and Simulation.
