Design-Oriented Transient Stability Analysis of PLL-Synchronized Voltage-Source Converters [PDF]
Differing from synchronous generators, there are lack of physical laws governing the synchronization dynamics of voltage-source converters (VSCs). The widely used phase-locked loop (PLL) plays a critical role in maintaining the synchronism of current ...

Ultrasound array transmitter architecture with high timing resolution using embedded phase-locked loops [PDF]
Coarse time quantization of delay profiles within ultrasound array systems can produce undesirable sidelobes in the radiated beam profile. The severity of these sidelobes is dependent upon the magnitude of phase quantization error - the deviation from ...

Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters [PDF]
This paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference frame phase locked loop (PLL).

Grid-Synchronization Stability Analysis for Multi DFIGs Connected in Parallel to Weak AC Grids
Recent works have shown that phase-locked loop (PLL) synchronized wind turbines (WTs) suffer stability issues when integrated into weak grids. However, most of the current studies are limited to a single machine case, the interactions among the WTs are ...

Low-Jitter Clock Multiplication: a Comparioson between PLLs and DLLs [PDF]
This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume
