Rijkeboer, Mats (author)Highly accurate time sources, such as Cesium-based or GPS clocks, are the best candidates to provide a correct notion of time, but are too costly and impractical for implementation in every modern digital device. Ubiquitously, (crystal) oscillators are employed instead. To maintain a shared notion of time, the offsets and drift/jitter have to be...master thesis 2023

Lu, T. (author), Du, S. (author)In this letter, a 6.78-MHz single-stage regulating voltage-doubling rectifier is presented for biomedical wireless power transfer (WPT) applications. Derived from a full-wave voltage doubler, a theoretical voltage conversion ratio (VCR) of 2 can be achieved, which benefits the end-to-end voltage gain of a biomedical WPT system with varying...journal article 2023

Dong, J. (author), Sharifi K., Arman (author), Mohajerin Esfahani, P. (author)We study a diagnosis scheme to reliably detect the active mode of discrete-time, switched affine systems in the presence of measurement noise and asynchronous switching. The proposed scheme consists of two parts: (i) the construction of a bank of filters, and (ii) the introduction of a residual/threshold-based diagnosis rule. We develop an...journal article 2023

Wu, Huan (author), Luo, Houcai (author), Zhang, Jingping (author), Zheng, Bofeng (author), Lang, Lei (author), Wang, Zeping (author), Zhang, Kouchi (author), Chen, Xianping (author)To investigate the unclamped inductive switch (UIS) characteristics, 1200 V silicon carbide (SiC) planar MOSFETs with four cell topologies of linear, current sharing linear, square, and hexagon are designed and manufactured. The experimental platform was built and tested. The results show that the single pulse avalanche energy density of the...journal article 2023

Moposita, Tatiana (author), Garzon, Esteban (author), Crupi, Felice (author), Trojman, Lionel (author), Vladimirescu, A. (author), Lanuzza, Marco (author)This brief deals with the impact of spin-transfer torque magnetic random access memory (STT-MRAM) cell based on double-barrier magnetic tunnel junction (DMTJ) on the performance of a two-layer multilayer perceptron (MLP) neural network. The DMTJ-based cell is benchmarked against the conventional single-barrier MTJ (SMTJ) counterpart by means...journal article 2023

Hua, Yuan (author), Lu, Qi (author), Li, Shuangmu (author), Zhao, B. (author), Du, S. (author)This brief presents a 48V-to-1V 10-level dual inductor hybrid converter (DIHC) containing 11 on-chip switches and an off-chip gallium nitride (GaN) switch. Thanks to the 10-level Dickson switched-capacitor (SC) circuit, most of the voltage stress will be taken over by off-chip capacitors, which reduces the voltage stress of each switch to 4.8...journal article 2023

Lu, Qi (author), Li, Shuangmu (author), Zhao, B. (author), Jiang, Junmin (author), Chen, Zhiyuan (author), Du, S. (author)Multiple voltage conversion ratio (VCR) recursive switched-capacitor (SC) dc-dc converters, based on several basic 2:1 converters, are widely used for on-chip power supplies due to their flexible VCRs for higher energy efficiency. However, conventional multiple VCR SC converters usually have one or more 2:1 converters unused for some VCRs,...journal article 2023

SUN, JIAN (author)An efficient, compact, and lightweight three-phase AC-DC power factor correction (PFC) converter becomes a necessity for the On-board chargers (OBCs) of the electric vehicle (EV) in conventional grid-to-vehicle (G2V) and vehicle-to-grid (V2G) charging scenarios. The commercially available OBCs have very limited power density despite the moderate...master thesis 2022

Smeets, Lucy (author)Sorting systems form an example of event driven systems. These types of systems are referred to as discrete event systems (DES), and they consist of jobs that need to be performed at available resources. In an autonomous sorting system, jobs consist of robots receiving and delivering parcels at the correct locations. With scheduling, optimal...master thesis 2022

Hoogerwerf, Samuel (author)The goal in this thesis is to make a prediction on the total processing time for logistical systems to complete their tasks. For simple systems that can be described using a regular max plus state space model this is done by calculating the systems eigenvalue and multiplying that by the number of iterations required. But, for more complex...master thesis 2022

de Jong, Bart (author)Switching max-plus linear (SMPL) systems written in max-plus algebra form a robust framework to model discrete-event systems governed by synchronisation whose behaviour may switch over time. Their evolution is described by a max-plus linear state-space representation that may change by switching modes. In their typical form, switching may depend...master thesis 2022

Mortier, Lucas (author)Dit rapport behandelt een wissel die geen bewegende delen bezit en hierdoor geen controle circuit nodig heeft. Het rapport bezit een analyse van verschillende bestaande wissels en wisselconcepten, beide in hoofdspoor en tramspoor, om een evaluatie te geven van elk concept. Op deze manier is bepaald of een zodanig "statische wissel" wenselijk is...bachelor thesis 2022
