设计了一种新颖的三相锁相环的设计算法，可以用于不平衡电压的相位检测和跟踪。-A modified soft phase lock loop algorithm improving the performance inDynamic phase tracking and detection of unbalanced voltage

Phase Locked Loops (PLL) Introduction to PLL The concept of Phase Locked Loops (PLL) first emerged in the early 1930’s.But the technology was not developed as it now, the cost factor for developing this technology was very high. Since the adva
