A mode switching based transient ride‐through phase‐locked loop
IET Power Electronics, 2023 In the case of grid voltage quality problems, the traditional phase‐locked loop (PLL) is hard to detect the accurate grid frequency and phase during the transient response, which will be detrimental to the transient synchronous stability of grid ...

Coherent beam combining with multilevel optical phase-locked loops [PDF]
, 2007 Coherent beam combining (CBC) technology holds the promise of enabling laser systems with very high power and near-ideal beam quality. We propose and demonstrate a novel servo system composed of multilevel optical phase lock loops.
