Abstract
This research examines the issues with harmonics in a voltage source inverter (VSI) and proposes the cuckoo search optimization (CSO) algorithm for reducing THD value. This algorithm has been employed to estimate the optimum values of the PI constants. Utilizing the traditional PI controller attached VSI, the tuned values of PI constants determined by the CSO algorithm are employed to reduce harmonics. The Simulink tool of the MATLAB program and the hardware configuration employing the PIC microcontroller were used to carry out the experimental verifications. The estimated THD values for both the software and the hardware results demonstrate that the THD values are significantly lower than the requirements set out by the IEEE standard.
