| Abstract: | Usually grid current contains large amounts of harmonic currents,but the traditional PI control can not real-ize accurate waveform tracking.To solve this problem,a hybrid control method including proportional control and repetitive control is adopted in current loop controller design.The characteristics of both amplitude frequency and phase frequency of control object are adjusted through series rectification,and steady state performance is improved and dynamic response speed could be guaranteed owing to re... |
