Web3.1 sogi-pll小信号模型. 第2节所述诺顿等效方法，忽略了锁相环环节。但实际上，锁相环是并网逆变器的重要控制环节，对系统稳定性有重要影响[10-12]。为此，本文对现有诺顿等效电路模型进行修正，增加锁相环影响。 WebThe phase-domain model is treated as a multi-input single-output (MISO) system. The inputs model perturbations at various nodes in the PLL. The effect of noise disturbances on the reference input, charge pump, loop filter, and VCO is analyzed to see what effect such noises have on the PLL’s overall phase noise.
