Fully differential electro-mechanical phase locked loop sensor circuit [PDF]

, 2013
Embedding a micro-machined sensing element in a closed loop, force feedback system is a technique commonly used to realise high performance MEMS (micro-electro-mechanical systems) sensors due to the advantages of better linearity, increased dynamic range

Three‐Dimensional Anomalous Hall Sensing Enabled By Spin–Orbit Torque Driven Domain Reconfiguration In Chiral Multilayers

Advanced Functional Materials, Volume 36, Issue 70, 31 August 2026.
A three‐dimensional magnetic field sensor is realized in chiral W/CoFeB/MgO multilayers, where spin–orbit torques reversibly reconfigure homochiral stripe domains. The symmetry of the torque enables offset‐free in‐plane sensing, while the reproducible domain reconfiguration extends the linear out‐of‐plane range. An anomalous Hall readout delivers large‐

Phase-Locked Strategy of Photovoltaic Connected to Distribution Network With High Proportion Electric Arc Furnace

IEEE Access, 2020
With the rapid development of industrialization, the proportion of electric arc furnaces (EAF) in distribution networks is getting higher and higher. Aiming at the problem that grid voltage is distorted by a large number of arc furnace nonlinear loads ...

Transient Response Analysis of Quasi‐Synchronization and Self‐Synchronization Grid‐Connection Processes for Nuclear Power (N + X) Emergency Diesel Generator Units

Engineering Reports, Volume 8, Issue 8, August 2026.
The upper portion condenses the five‐unit EDG arrangement into repeated diesel–governor and generator–AVR modules, distinguishing four operating units from one standby unit. Measured data and the equipment configuration jointly support a calibrated full‐system model, which then feeds two parallel research tracks covering self‐synchronization and quasi ...

An adaptive gain phase‐locked loop for position sensorless control of permanent magnet synchronous motor drives

IET Electric Power Applications
In view of the cost and reliability issues caused by mechanical position sensors, position sensorless control (PSC) of permanent magnet synchronous motors (PMSMs) has received widespread attention. A series of rotor position estimation (RPE) schemes have

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS

Radio Science, Volume 61, Issue 8, August 2026.
Abstract During deep space missions, maintaining reliable communication between a spacecraft and Earth becomes particularly challenging during superior solar conjunctions, when the spacecraft passes behind the Sun relative to Earth. The highly ionized solar corona and solar wind create plasma inhomogeneities that severely affect radio signals, leading ...

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...
