Design of Multilevel Inverters for Electric Vehicle Applications

Abstract

Due to its small size and great efficiency, multilayer inverters (MLI) are used in a variety of industries, most notably solar photovoltaics (PV) and electric vehicles (EV) (EV). Based on these findings, we present a 53-level Multilevel Inverter Design using Switched Capacitors (SC). The total number of SC cells is an important element in determining MLI concentration. SC cells have been measured to have end-to-end voltages between 17 and 33 volts. The suggested structure is so simple that even top-level executives shouldn't have any trouble adapting to it. By reducing the number of active switches, the size of driving circuits may be minimized. A reduced carbon footprint and cheaper manufacturing costs are the result of an MLI's simplified design and lower development expenditures. Utilizing a multi-output converter and the perturb and observe (P&O) method, the DC connection voltage may be increased beyond the stable DC voltage given by the solar panels (SIMO). All of the proposed inverters are subjected to rigorous experimental testing under real-world conditions including varying loads and temporary power interruptions. Watch this video to see an electric car being put through its paces on a number of different terrains. We examine and evaluate several different parts, including switches, gate driver boards, sources, diodes, capacitors, and the overall amount of parts. Total harmonic distortion (THD) must be less than 5% throughout all three MLI simulations to meet IEEE requirements (17, 33, and 53 levels). We are now doing simulations in MATLAB/Simulink and building a hardware prototype.
