Analysis of a Fuzzy Logic Controller-Based Power Electronics for Electric Vehicle-Based Ac/Dc/Ac Power Conversion System

Abstract

Electric motors are replacing the Internal Combustion Engine (ICE) because they are more environmentally friendly and efficient. When it comes to the electric vehicle, battery and ultra-capacitor technology play crucial roles. The battery or ultra-capacitor of a plug-in EV is charged by an external AC supply connected to the grid line, while the battery or ultra-capacitor of a hybrid EV is charged by the internal combustion engine. Regenerative braking makes use of the traction motor to replenish the battery. Energy is transferred backwards from the AC grid line into the battery or ultra-capacitor, thereby powering the vehicle in reverse. Power electronic converters provide for the safe and efficient transfer of energy between the grid and the traction motor. Power electronics converters in an EV are the subject of extensive analysis. In this article, we investigate the power factor adjustment strategies utilised by single-phase AC/DC-DC power electronic converters installed in electric vehicles. Power factor correction (PFC) efficiency can be improved by employing a variety of solid-state DC-DC converters to keep up with the growing power demand. In order to evaluate the converters, the simulated data, such as power loss estimates and a harmonic analysis, are analysed and compared with fuzzy logic controller
