Rectifier plays a pivotal role in wireless power transfer systems. While numerous studies have concentrated on enhancing efficiency and bandwidth at specific high-power levels, practical scenarios often involve unpredictable inputs. Consequently, distinct need arises for rectifier that demonstrates superior across broad range of input levels. This paper introduces RF-to-DC designed WPT applications, featuring an ultrawide dynamic power. The rectification process leverages GaN (gallium...
This paper presents a 20 W high-power RF-to-DC rectifier that can be applied to wireless power transfer (WPT) systems. To address the limitations of conventional diodes, is designed based on gallium nitride (GaN) integrated circuit (IC) quasi-vertical Schottky barrier diode (SBD). Leveraging advantages high mobility, wide bandgap, and saturation velocity GaN, significant benefits have been derived, with an ultra-low turn-on voltage 0.23 ± 0.005 V (at 1 A/cm <sup...
With the continuous development of modern society, construction transmission network has been rapidly advanced, and reliability power supply fundamentally improved, but workload detecting insulators also increased. In order to further reduce tripping rate line, insulator fault detection work cannot be delayed. However, traditional method low efficiency, poor safety high cost, which meet requirements. This paper proposes a applying ultrasonic technology line by referring application in United...
In this paper, we research the safety perception of pedestrian crossings under different crosswalk conditions and analyze causes conflicts between pedestrians other traffic participants. We also offer suggestions on clearance mitigating turning. The study conducted intercept surveys at crosswalks in Shanghai, where were asked to rate their perception. result is late walkers (LW) have worst perception, while green (GW), red (RW) a similarly higher Results show that improved with presence...
Abstract Because the distribution power network is very complex, and easy to cause trouble, The signal too small be submerged in noise, So it hard find where fault from branches. based on distributed parameter model of transmission lines, this paper proposes a location method multi branch lines lines. It will affect whole generate faults. Find line through analysis, then point that calculation simulation results prove correctness accuracy method, provide theoretical basis for
