“…Since the OHT system has more than one Rx pickup structures on its MSWPT, a multi-load system is not the focus of this study, and, therefore, it is not The structure on the Tx side that transfers energy to the pickup coil is a long single-turn track with a constant high-frequency current, so the coil loss P con1 on the transmitter side should be determined by the track length. η = P out P out + P loss (20) According to the formulas for calculating losses and efficiency, the primary losses on both the transmitter and receiver sides are predominantly concentrated in the heat generated by the coil's AC internal resistance. In the state where the magnetic core is not saturated, the core loss accounts for a smaller proportion of the total loss.…”

“…In [18], the authors introduced a simulator with a Tx-end buried I-shaped magnetic core and a DQ-phase receiver (Rx) structure capable of accurately simulating and testing a wide range of driving speeds and investigating the resonant current stress on the receiver end. Most of the above WPT systems were studied with flat-plate magnetic coupling mechanisms, while the development of the orbital wireless power supply originated at the University of Auckland, New Zealand [19] and has gradually been further developed and diversified by scholars and companies in various countries [20,21]. These scholars have made pivotal contributions to the industrial and industrial aspects of WPT, but little has been said about the design thinking of magnetically coupled mechanisms.…”

To tackle the complex wireless power supply requirements in the Automated Material Handling System (AMHS) of semiconductor wafer factories, this paper presents a design method for a magnetic coupling mechanism based on a Multi-Segment Wireless Power Transfer (MSWPT) system for dynamic wireless power supply in segmented track configurations. Firstly, the track is approached using Inductive Power Transfer (IPT) technology combined with an LCC-S resonant structure transmitter (Tx). Following this, the feasibility of the H-type pickup is assessed through magnetic and electrical circuit analyses, which leads to the preliminary determination of the pickup dimensions by means of finite element magnetic and thermal simulations. Furthermore, an analysis of the mutual inductance drop is conducted under various track structure parameters during track crossing and curve negotiation operation conditions. Secondly, a dual-coil winding method is proposed to reduce the insulation stress on the PCB board. Additionally, a method for calculating the wire length and a design process for the overall parameters of the pickup are derived. Finally, two Txs and a 1.5 kW power receiver (Rx) were designed to verify the mutual inductance fall under the aforementioned conditions. During low-speed full-load operations, a constant-voltage output was achieved through the proposed dual-loop PI control strategy, thereby meeting the requirements for a constant-voltage output in industrial applications.

“…A distributed ledger technology contains a list of append-only, timestamped transactions encrypted and backed by consensus mechanisms. In peer-to-peer networks, immutable records are permanently stored over a decentralized network of equal peers (Hwang et al ., 2018). Several decades have passed since blockchain technologies were first developed (e.g.…”

PurposeThis paper aims to assess the readiness of retail workers to use blockchain technology (BCT) to improve supply chain performance. The assessment was made via a quantitative approach taken using a theoretical framework based on Keller’s motivation model and self-determination theory in the BCT context.Design/methodology/approachThe authors collected data from 567 retail workers from an emerging country through a structured survey questionnaire. The authors tested the hypotheses of the proposed model using Warp PLS 7.0 and controlled firm age, industry type and technological intensity.FindingsOur findings may help firms in making the process of digital transformation inclusive. The authors found that supplier-based attention and motivation through BCT lead to supply chain performance, and that supplier-based satisfaction and trust achieved through BCT positively impact supply chain performance. Further, supplier-based relevance on raw material selection with the higher trust and motivation levels achieved through BCT was found to have a positive impact on supply chain performance.Research limitations/implicationsIT supply chain applications are referred to as “lean” rather than “rich” because they still rely mainly on written and numerical means to present data. When the environment is less ambiguous, then less rich media can be used to facilitate communication. IT supply chain applications allow suppliers to spend time building relationships with other suppliers instead of focusing on administrative tasks, thus enhancing such relationships.Originality/valueThis study can be considered the first to assess retailer readiness to use BCT to improve supply chain performance through the theoretical lens of Keller’s motivation model and self-determination theory.
