| Abstract: | It is presented a novel three-phase hybrid active power filter with series resonance circuit turned at fundamental frequency. The topology and the main characteristics of the filter are discussed. Then the principles of the filter selecting the control strategy based on detecting grid current are addressed, which equivalently enhancing the harmonic impedance in the grid by controlling the active power filter effectively. At last, the steady-state compensation characteristics are analyzed on the consideration of damping the resonance probability between the grid and the passive filters, enhancing the filtering effects of the passive filters and improving the robustness of the total system. |
