基于多电平矢量发生的逆变实验系统设计

Design of Invert Experiment System Based on a Multilevel Vector Generating

空间矢量发生是SVPWM的关键环节。矢量发生器的出现,使多电平SVPWM研究进一步类同于两电平SVPWM,研究者只需考虑算法问题,而无需担心其实现问题,这无疑会给研究带来极大的方便。文章根据矢量发生器特性,制作了一套实验系统,实验结果表明基于DSP和FPGA的多电平矢量发生逆变器的可行性。

Generation of spatial vector is a crucial step towards the SVPWM. Vector generator makes the research of multilevel SVPWM as convenient as that of bilevel SVPWM, so that researchers can pay their attention on the issue of arithmetic and ignore the generating stage. Based on the features of vector generator, a experiment system is designed to testify the feasibility of multilevel vector generator in terms of DSP and FPGA.
