Investigation Into Active Gate-Driving Timing Resolution and Complexity Requirements for a 1200 V 400 A Silicon Carbide Half Bridge Module

Autor: Mason Parker, Ilker Sahin, Ross Mathieson, Stephen Finney, Paul D. Judge

Publikováno v: IEEE Open Journal of Power Electronics, Vol 4, Pp 161-175 (2023)

Silicon Carbide MOSFETs have lower switching losses when compared to similarly rated Silicon IGBT, but exhibit faster switching edges, larger overshoots and increased oscillatory switching behaviour, resulting in greater electro-magnetic interference

Model Predictive Controller Utilized as an Observer for Inter-Turn Short Circuit Detection in Induction Motors

Autor: Ilker Sahin, Ozan Keysan

Publikováno v: IEEE Transactions on Energy Conversion. 36:1449-1458

In this paper, a novel and non-invasive stator inter-turn short circuit (ITSC) online detection method is presented for an induction machine (IM), driven by a two-level voltage source inverter (2L-VSI) via finite control set model predictive control

Investigation into active‐gate‐driving performance and potential closed‐loop controller implementations for silicon carbide MOSFET modules

Autor: İlker Şahin, Mason Parker, Ross Mathieson, Stephen Finney, Paul D. Judge

Publikováno v: IET Power Electronics, Vol 17, Iss 12, Pp 1540-1551 (2024)

Abstract Active gate driving (AGD) is a promising concept for achieving high‐performance power transistor switching. This is particularly crucial for Silicon Carbide (SiC) MOSFETs since their inherently fast switching characteristics give rise to s

Experimental tuning and design guidelines of a dynamically reconfigured weighting factor for the predictive torque control of an induction motor

Autor: Eric Monmasson, Ozan Keysan, Ilker Sahin

Publikováno v: 2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)
2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe), Sep 2020, Lyon, France. pp.1-8, ⟨10.23919/EPE20ECCEEurope43536.2020.9215739⟩

In this study, an experimental approach for the weighting factor design of the predictive torque control of an induction motor (IM) is presented. The weighting factor is set to the value which yields a low total harmonic distortion (THD) figure in th

A Simulink Model for the Induction Machine with an Inter-Turn Short Circuit Fault

Autor: G. H. Bayazit, Ilker Sahin, Ozan Keysan

Publikováno v: 2020 International Conference on Electrical Machines (ICEM).

In this study, an analytical model for the induction machine (IM) with an inter-turn short circuit (ITSC) fault is developed based on the voltage-behind-reactance (VBR) approach. The main motivation is to provide a simulation tool that can be used fo
