A master’s thesis in the Department of Electrical and Electronic Engineering at the College of Engineering at the University of Karbala discussed the performance of electric vehicles through the use of a high-performance multilevel inverter as well as a hybrid feeding system with the tagged thesis.
((Design of high-performance multi-level inverters for a battery-PV hybrid electric vehicle))
Which was presented by researcher Nafi’ Mahdi Issa. The study aims to improve the performance of brushless direct current (BLDC) motors in electric cars through the use of a multi-source system that includes a battery and solar panels in addition to a super capacitor to feed the motor through a traditional inverter and a multi-level inverter. In addition to designing controllers to control the motor speed using the traditional PI controller and the SMC controller for the traditional inverter and the multi-level inverter, the engine performance was compared for both cases.
The thesis concluded through the results that advanced control methods using SMC with a multi-level inverter significantly improved the torque ripple and reduced harmonics and starting current, which led to energy savings and increased efficiency.
The thesis was approved by the discussion committee, which consisted of Professor Dr. Ali Abdel-Razzaq (University of Kerbala, College of Engineering/Chairman), Assistant Professor Dr. Marwa Muhammad Mar’i (Faculty of Engineering/University of Kerbala), and Assistant Professor Dr. Muhammad Ahmed Abdullah (Al-Hussein National College, Department of Medical Devices).
