三相-单相矩阵变换器容错控制与输入电流优化
|
摘要
为提高三相-单相矩阵变换器(3-1MC)的供电可靠性,针对开关元件的开路故障与短路故障,研究了3-1MC的容错控制调制策略并设计了带解耦电感的容错控制拓扑。利用快速熔断器将短路故障转换为开路故障,将2种故障归结为开路故障,并对不同桥臂的开路故障控制策略进行了分析与计算。为实现输入电流的优化,提出对补偿电感进行功率解耦、中线电流补偿及退出运行等策略。通过仿真与实验对所设计的容错控制策略进行了验证,结果表明,在硬件改动较小的前提下,在不同桥臂故障下3-1MC均能维持输出电压稳定,同时输入电流的畸变较小。
In order to improve the power supply reliability of 3-1 MC(three-phase to single-phase Matrix Converter),aiming at the open circuit fault and short circuit fault of switch elements,the fault-tolerant control strategy of 3-1 MC is studied and the fault-tolerant control topology with decoupling inductance is designed. The short circuit fault is converted into an open circuit fault by using fast fuse,and then the two kinds of faults are classified as open circuit faults. The open circuit fault control strategies of different bridge arms are analyzed and solved. In order to realize the optimization of input current,the strategies for compensation inductance of power decoupling,middle line current compensation and exit operation are put forward. The proposed fault-tolerant control strategy is verified by simulation and experiment. Results show that,based on the small change of hardware,the output voltage stability of 3-1 MC can be maintained under different bridge arm faults with small input current distortion.
