A simple and efficient control strategy for three-phase boost rectifiers

Performance criteria of three-phase boost rectifiers improve significantly with increasing the switching frequency, and highly depend on the control strategy used. This paper introduces a modified vector classification SVM-based control strategy for three-phase boost rectifiers. By means of the proposed technique abc-dq and dq-/spl alpha//spl beta/ transformation carried out in conventional SVM-based strategies are avoided. Therefore current regulators in d-q frame and also control difficulties associated with them are removed. In addition, the proposed technique maintains the advantages of other schemes. Simulation results provided, confirm the validity of the analytical work.
