This paper studies the principle of an active filter performing real-time compensation for harmonic currents, either stationary or non-stationary. The rnodelling of the active filter with an output filter (Lf, Cf) used to attenuate switching ripple, is given. Real-time compensation is provided by fast regulation of harmonic currents. Regulation robustness is then analyzed. Associating a prediction with the regulation makes it possible to improve compensation behavior. Simulation results, taking into account practical conditions, show excellent compensation of harmonic currents. |
