IEEE AccessSynchronization of single-phase inverters is a challenging task due to the difficulty of deriving a rotating voltage frame, in the absence of adequate information from the other two phases. Moreover, modern standards, such as the fault ride-through (FRT)

A generalized phase resetting method for phase-locked modes prediction. [PDF]
PLoS ONE, 2017 We derived analytically and checked numerically a set of novel conditions for the existence and the stability of phase-locked modes in a biologically relevant master-slave neural network with a dynamic feedback loop.

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Noise performance of frequency- and phase-locked CW magnetrons operated as current-controlled oscillators. [PDF]
, 2005 Low-power continuous wave ``cooker'' magnetrons driven from industrial-quality switch-mode power supplies have been frequency locked by driving them as current-controlled oscillators in a phase-lock loop (PLL).

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

A high-efficiency RF transmitter using VCO-derived synthesis: CALLUM [PDF]
, 1998 The combined analog locked-loop universal modulator (CALLUM) is a radio-frequency (RF) transmitter topology which produces a linear output through the use of nonlinear, but highly efficient, RF power amplifiers.

Synthesis of Phase-locked Loop System Structure with Adaptation Based on Combined-maximum Principle
MATEC Web of Conferences, 2016 The synthesis of the structure of the phase-locked loop system is performed based on the generalized power function maximum condition. The system effectiveness in the lock-on mode is studied via numerical simulation.

Transactions on Environment and Electrical Engineering, 2016 Proper synchronization of Distributed Generator with grid and its performance in grid-connected mode relies on fast and precise estimation of phase and amplitude of the fundamental component of grid voltage. However, the accuracy with which the frequency
