摘要

模块化多电平矩阵变换器$(M^{3}C)$由于具有中压运行和电能质量的特点，已被提出作为大功率驱动系统的合适替代方案。然而，M^{3}C$的控制是复杂的，特别是在变速应用中，因为浮动电容器中可能产生较大的电压振荡。因此，本文提出了一种矢量控制系统，该系统允许对M^{3}C$的浮动电容进行解耦调节，而磁场定向控制(FOC)则应用于感应电机的调节。提出的控制策略考虑了不同负载条件下机器的增强启动。

Vector Control of a Modular Multilevel Matrix Converter for Variable-Speed Drive Applications

The Modular Multilevel Matrix Converter $(M^{3}C)$ has been proposed as an appropriate alternative for high-power drive systems due to characteristics for medium-voltage operation and power quality. Nevertheless, the control of $M^{3}C$ is complicated, especially in variable-speed applications, because large voltage oscillations can be produced in the floating capacitors. Therefore, this paper presents a vector control system that allows decoupled regulation of the floating capacitors of the $M^{3}C$, whereas Field Oriented Control (FOC) is applied to regulate an induction machine. The proposed control strategy considers an enhanced start-up of the machine for different load conditions.
