| 摘 要： | 与传统的频率变换器相比,矩阵变换器能够实现功率的双向流动,驱动电机四象限运行,输入端功率因数可调节为1,输出电压幅值、相位和频率可独立调节等优点。由于矩阵变换器的一般控制算法为开环控制,使当输入存在干扰时,输出电压的质量就会受到影响。采用一种基于电压滞环控制的闭环控制策略,对电压进行闭环控制,并在Matlab环境下建立仿真模型,仿真结果表明该控制算法是可行和有效的。

| Abstract: | Compared with the traditional frequency converter,the matrix converter has the advantages of the u-nity input power factor,bi-directional power flow,four quadrants operation of the induction motor,indepen-dently regulation of the output voltage phase and frequency. The general control method of the matrix convert-er is open loop control,such as direct control and space vector control,which can highly influence the quality of the output voltage when the input voltage has disturbance. A closed loop control method based on the volt-age hysteresis band control has been introduced in the paper to realize the closed loop control of the output voltage. And a simulation model has been built based on the Matlab software, the simulation result proved the good performance of the controller. |
