Design optimization for minimizing cogging torque in axial flux permanent magnet machines Vrije Universiteit Brussel
This paper deals with the optimization of a single side Axial Flux Permanent Magnet machine (AFPMM) designs with respect to cogging torque. Although the AFPMMs run generally at high speed and high torque, these machines may run at lower operational speed for aircraft applications. At lower operational speed, the cogging torque is an undesirable effect. Firstly, a reference AFPMM is designed with Finite Element Methods (FEM) and is analyzed ...
Environmental impacts of a hydrometallurgical process for electronic waste treatment Vrije Universiteit Brussel
The recovery of precious metals through hydrometallurgical techniques is one of the most active research areas on recovery of metals from electronic scraps. In this perspective, a pilot plant was designed for the treatment of small WEEE (Waste Electrical and Electronic Equipment) via hydrometallurgy. The process is based on two different leaching steps, in nitric acid and in aqua regia, followed by electrodeposition processes, to mainly ...
Application considerations for Double Sided Cooled Modules in Automotive Environment Vrije Universiteit Brussel
Advanced Edge Computing Framework for Grid Power Quality Monitoring of Industrial Motor Drive Applications Vrije Universiteit Brussel
In large-scale industrial machine applications (IMAs) during condition monitoring, all sensor devices can produce raw data up to 15TB of data/week. Transmitting these large high-frequency data sets to the cloud to closely monitor the operational environment and make decisions is not feasible for two reasons: (a) bandwidth and latency issues and (b) higher cost of data transfer and storage. Condition monitoring applications usually extract ...
Real-Life Mission Profile Oriented Lifetime Estimation of a SiC Interleaved Bidirectional HV DC/DC Converter for Electric Vehicle Drivetrains Vrije Universiteit Brussel
The rapid growth of Battery Electric Vehicles (BEVs) in the automotive field has led to a need for improving their drivetrain performance, mainly focusing on the extension of the battery operating range. However, the majority of performed technical assessments only consider battery SoC and depth of discharge while neglecting the effects on lifetime and failure probability of power electronic components, more specifically the emerging ...
Active Thermal Control of a WBG-based AC-DC Converter Using Dynamic Gate-drive for Lifetime Improvement Vrije Universiteit Brussel
In this paper, an advanced method for implementing active thermal control is proposed that can be helpful for smoothing repetitive junction temperature swing, which is one of the main reasons for wear-out failure in Wide bandgap (WBG)-based (i.e., SiC) power electronics converters (PEC). Utilizing current-source gate-drive, rise/fall (tON/tOFF) time during switching transition can be controlled, resulting in shaping switching losses in the ...
