矩阵变换器应用于电机系统的研究与进展

Review of Matrix-Converter Application in Electric Machine Systems

矩阵变换器(Matrix converter,MC)是一种直接变换型的交流-交流电力变换装置,具有无电解电容、结构紧凑、功率密度高和恶劣环境条件下适应性强等优点,适用于电机驱动、移动电源和风力发电等场合,因此得到了国内外众多学者的关注。本文主要对MC在电机系统中应用的研究现状进行综述。首先对MC在异步电机、同步电机以及在航空作动器等电机驱动系统中的研究现状进行了评述,然后介绍了MC应用于基于燃气轮机的分布式发电系统和大功率风力发电中的发展现状,最后对MC在工业界的发展情况进行介绍。本文的内容对矩阵变换器的进一步研究及其推广应用具有参考价值。

Matrix converter （MC） is a direct AC-AC power converter without any electrolytic capacitors. The advantages of MC, such as compact structure, high power-density and high adaptability in severe environment, make it suitable for the application of motor drive, mobile power utility and wind power generation. Therefore, MC has been a hot topic of research for last decades. The state of the art in the MC^s applications in electric machines is presented in this paper. Firstly, the research status of MC- based driver for induction motors, synchronous motors and aircraft actuators is reviewed; then, the ap- plication of MC in gas-turbine-based distributed generation systems and high-power wind generation sys- tems is introduced; finally, the development of MC in industry is presented. This paper will be a valua- ble reference for further research and industrial application.
