摘要
This paper presents a simplified SVM for Vienna-type rectifier which is based on the space vector modular of a three-level converter into a two-level converter, the dwelling time calculation and switching sequence selection are easily done like conventional two-level rectifier, which is discussed in detail in this paper. Meanwhile, based on inherent correlation between carrier-based PWM and SVM for three-level converter, the equivalent carrier-based PWM for Vienna-type rectifier is derived by injecting the optimum zero-sequence vector. In addition, the neutral point voltage unbalance problem is solved successfully by utilizing the proposed equivalent SVM algorithm. Simulation models in Matlab/Simulink and a DSP-controlled 10kW Vienna-type rectifier are used to verify the proposed method is feasible and efficient for Vienna-type rectifier.
