Description
Summary:In order to improve the current tracking performance of shunt active power filter and reduce the switching frequency, in this paper, two kinds of space vector control strategies are studied. The double hysteresis current control method based on voltage space vector (DHCC-SVM) is introduced specifically. This method chooses the optimal output voltage vector through judging the space distribution of current error vector and reference voltage vector, therefore the current error is controlled below the hysteresis band, which can decrease the switching frequency and improve the efficiency of APF evidently. The simulation results show the feasibility and effectiveness of the introduced method.
