Binary phase detector gain in bang-bang phase-locked loops with DCO jitter [PDF]
, 2010 Bang-bang phase-locked loops (BBPLLs) are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). In the presence of jitter, the nonlinear loop is typically analyzed by linearizing the BPD and applying linear ...

FPGA implementation of impedance-compensated phase-locked loop for HVDC converters
The Journal of Engineering, 2018 The phase-locked loop (PLL) plays a key role in HVDC systems. Recently, a new type of PLL called the impedance-compensated phase-locked loop (IC-PLL) was introduced to compensate for the voltage drop across the AC network's Thevenin impedance, making the

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems
Energy Science &Engineering, EarlyView.This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...
