Tekgun, Didem; Tekgun, Burak; Alan, Irfan (SPRINGER, 2022)In this paper, a finite element analysis (FEA) based fast optimization method to optimize a lightweight in-wheel switched reluctance machine is presented. This method speeds up the switched reluctance machine optimization ... -
Investigating the Role of Stator Slot Indents in Minimizing Flooded Motor Fluid Damping Loss
Tekgun, Didem; Tekgun, Burak (MDPI, 2023)This research examines how fluid damping loss affects the operation of a two-pole, 5.5 HP (4 kW) induction machine (IM) within the context of different slot opening configurations developed for downhole water pump ... -
Investigating the Tradeoff Between the MMF Distortion and End Turn Length of a 2-Pole Line Start SynRM Performance
Tekgun, Didem; Cosdu, Muhammed Muhsin; Tekgun, Burak; Alan, Irfan (Institute for Ionics, 2023)Conventional 2-pole AC machine windings have long end windings and generate harmonics, which increase losses and reduce torque density. This study investigates the performance tradeoff between the level of distortion (THD) ... -
Modified Induction Machine Equivalent Circuit Including Solid Shaft Eddy Currents
Tekgun, Didem (MDPI, 2023)The shaft eddy currents cause a significant saturation in two-pole induction machines (IMs) as they generate an opposing field and repulse the main flux, thus tightening the flux path. This results in inaccurate performance ... -
A multi-functional quasi-single stage bi-directional charger topology for electric vehicles
Tekgun, Burak; Tekgun, Didem; Alan, Irfan (ELSEVIER, 2024)In this paper, a multi-functional quasi-single stage, bi-directional electric vehicle charger topology is proposed to realize high efficiency power conversion in all AC/DC, DC/DC, and DC/AC forms. The proposed circuitry ... -
