基于间接矢量调制矩阵变换器建模仿真研究
Modeling and Simulation Research based on indirect vector modulation matrix converter
Matrix converter has a gird side power factor, adjustable output voltage frequency, low input current harmonics, two-way flow of energy, without intermediate DC link and other advantages. This paper analyzes the matrix converter topology structure and provides the AC-DC-AC equivalent circuit. It also introduces the process of indirect vector modulation technology implementation and different steps of the calculation on key parameters and selection principles. In order to avoid the presence of traditional switching and indirect vector modulation shifting twice adversely and the effects of current and voltage waveform quality, this project has optimized the configuration of the modulation vector cycle. Finally, this paper studies the simulation through simulation software and analyzes the matrix converter harmonic simulation, then proves the effectiveness and feasibility of improved indirect vector modulation technology.
