基于d轴电压归一化的三相锁相环平衡点研究

Voltage normalization is usually adopted for a phase-locked loop (PLL) to keep a constant bandwidth unaffected from the voltage magnitude at the point of synchronization. Two conventional PLL normalization methods are analyzed from a large-signal perspective in this letter. However, different from the voltage magnitude normalization method, an unexpected stable equilibrium point emerges in the thr...
