Design and Harmonic Optimization of an IBC-Fed Multilevel Inverter Using Newton–Raphson and Particle Swarm Optimization Algorithms

Abstract

Electric vehicles will be an essential part of any future transportation system for their ability to boost fuel efficiency and energy security for the environment. At the present time, there are two kinds of two-level inverters available in this market. A five-level cascaded H-bridge multilevel inverter for Electric Vehicles application is proposed in this article. The newly suggested one can produce better quality output than the classic 2-level inverter. In general, the H-bridge inverter is used for generating 5 level output from two dc sources, in this work dc sources are replaced with renewable energy sources. Because of its abundant supply that is present in nature. The most used renewable energy system is photovoltaic cells. A constant DC output voltage from PV systems is desired with the proposed Interleaved Boost Converter. This DC-DC converter is used as a replacement of the DC sources in the multilevel inverter. The study of the boost converter and interleaved boost converter also showed the proposed integrated circuit is superior to the performance of EV propulsion and the reduction of EMI of the drive. Gate control logic in the inverter is developed based newton Raphson and particle Swarm optimization (PSO) eliminating the specific harmonic on selective Harmonic Elimination (SHE) PWM control logic is used in CML to even reduce the predominant harmonics and reduce the losses under different loading conditions. The simulation is carried out in MATLAB/SIMULINK considering various values of irradiation and temperature
