This paper analyses the configuration characteristics of the shunt active power filter (SAPF) and introduces a novel dead time control strategy in combination with three dimensional space-vector modulation (3D-SVM) strategies. The steps for the 3D-SVM implementation are identified. The switching vectors, 3D-SVM diagram and duty cycle calculation in abc coordinates, as well as the selection of the tetrahedron are discussed in detail. Moreover, based on the analysis of the APF’S dead-time effect with 3D-SVM control, a novel predictive direct current control algorithm is used for the APF’s inverter control. Experimental results together with different control strategy are presented to validate the proposed SVM control strategy for three-phase four-wire system. The experimental results verify the correctness and validity of the proposed 3D-SVM scheme.
