This paper discusses the analysis, simulation and experimental investigation of selective harmonics elimination with pulse width modulation using Newton-Raphson algorithm for three phase inverter. The purpose of using this modulation strategy is to increase the life span of the switching elements and improve the inverter output voltage. This study offers a general analytical description of the harmonic problem and explains the application of a Newton-Raphson algorithm for eliminating some target harmonics step by step. The accuracy of the method has been confirmed using MATLAB environment with a digital signal processor that goes by the name of Dspace 1104. The experimental results matches the simulation ones perfectly, thereby strengthening the previous studies about the effectiveness of the selective harmonics elimination based on Newton-Raphson algorithm.

Introduction. Currently, in the solar energy systems and a variety of electrical applications, the power converters are essential part. The main challenge for similar systems is controller design. In the literature, the PID controller has proved its effectiveness in many industrial applications, but determining its parameters remains one of the challenges in control theory field. The novelty of the work resides in the design and experimental implementation of a two-level boost DC-DC converter controlled by a PID controller for photovoltaic (PV) maximum power extraction. Purpose. Analysis and control of the two-level boost topology with renewable energy source and design of the PID controller parameters using simple and accurate method. Methods. PID coefficients are optimized using Coefficient Diagram Method (CDM) in the MATLAB environment. Results. A mathematical model of a two-level boost converter with PID controller and PV energy source was developed and analyzed. The model allows to design the controller parameters of the proposed system. Practical value. A prototype steered by the proposed CDM-PID controller was tested using an Arduino embedded board. A comparison between the simulation results and the experimental one is presented. The obtained results illustrate that the experimental results match the simulation closely, and the proposed CDM-PID controller provides a fast and precise results.

This research study provides the analysis, simulation, and experimental investigation of selective harmonic elimination with pulse width modulation for three phase inverter using the particle swarm optimization method. By employing this modulation technique, the inverter output voltage will be improved while the switching components' lifespan will be increased. The paper presents the harmonic issue in an analytical manner. The dSPACE DS1104 controller board, a digital signal processor, has been used with the MATLAB environment to verify the method's correctness. The experimental results closely approximate the simulation findings, supporting earlier studies about the efficiency of the particle swarm optimization based selective harmonic elimination.
