| Abstract: | The current digital phase lock technique for phase discrepancy do not have the active phase adjustment function.In this paper the problem is proposed based on both the phase offset the active phase adjustment new digital phase locked loop technique.The software is designd based on the TMS320F2407,and experiment is conducted.The experimental results show that grid current waveform is good,the real-time and dynamic response are better,and the design of the new digital phase locked loop technique is feasible. |
