| Abstract: | It introduces the SVC system based on the AADPLL(Advanced All Digital Phase-locked Loop)which adds self-adaptive mode control module to the traditional ADPLL.The system uses the technology for frequency multiplication phase-locked on the sampling.It multiplies by frequency of 6 on the sampling voltage to provide of the 6 trigger pulse,and multiplies by frequency of 128 to Sampling at 128 points per cycle.It gives the principle of the device hardware and the process of software.Simulations and physical exper... |
