Phase Locked Loop News Today

In a pre-proof study from the journal Optics Communications, the researchers present a method for generating linearly frequency swept optical waves using a digital optical phase-locked loop (OPLL).

While hitherto the synchronous grid is dominated by the synchronous generators (SGs), recently the grid-following inverter-based power generation systems (IBPGS) are increasingly being connected to the power grid, resulting in a slowly decreasing system total inertia impacting the operation of the power systems, in areas such as potential failures in the operation of phase-locked loops (PLLs), increased rate of change of frequency, contingency frequency control required during islanding conditio...

This webcast explores phase noise, as it relates to radio frequency applications, and mixed signal applications.

Abstract The use of different control techniques has become very popular for controlling the performance of grid-connected photovoltaic (PV) systems. Although the proportional-integral (PI) control technique is very popular, there are some difficulties such as less stability, slow dynamic response, low reference tracking capability, and lower output power quality in solar PV applications. In this paper, a robust, fast, and dynamic proportional-integral resonance controller with a harmonic and l...
