A Generalized Three-Dimensional Space-Vector Modulation Algorithm for Multilevel Converters
摘要
Abstract
The proposed three-dimensional (3D) space-vector modulation (SVM) algorithm maps switching state vectors in 3 D space coordinates directly. Every basic vector only matches a switching state vector. And without redundancy phenomenon. Firstly, the location of a unit cube which includes the reference voltage vector is fixed. Secondly, in the unit cube, four basic vectors which synthesize the reference vector are confirmed. The dwelling times of the basic vectors are calculated according to volt-second balance principle. Finally, switching among the four basic vectors is implemented by seven-segment modulation algorithm. Coordinate transformation is not required in this proposed algorithm. Reference vector location is fixed simply. The proposed algorithm is also independent of the level number of the inverter. The correctness and feasibility of this proposed algorithm are verified by the simulation and experimental results of a three-cell seven-level inverter.关键词
