电力行业中使用到的各种锁相环技术。This paper proposes a novel grid synchronization scheme using a new phase-locked loop (PLL) scheme based on the adaptive linear optimal filtering (ALOF) technique. The problem formulation of the proposed ALOF is based on decomposing
Abstract—An enhancement to a conventional integer- phaselocked loop (PLL) is introduced, analyzed, and demonstrated experimentally to significantly reduce voltage-controlled oscillator (VCO) phase noise. The enhancement, which involves periodically
