摘要:
针对双级矩阵变换器( TSMC) ,分别分析了 TSMC 正常与故障时的运行模式,分析并总结了TSMC 在功率开关故障情况下的输出线电压故障特征,在此基础上提出了基于开关组误差电压的TSMC 功率开关故障诊断方法,该方法可以根据开关组误差电压锁定故障开关组,并能从故障开关组中准确定位故障开关。该故障诊断方法具有快速、准确、高效等特点。建立了 TSMC 功率开关故障诊断系统的仿真模型和实验系统,验证了所提故障诊断方法的正确性和可行性。
Abstract:
 Taking two-stage matrix converter ( TSMC) as the research object,this paper analyzes the oper-ation mode of TSMC in normal condition and fault condition of power switch respectively,then analyzesand summarizes the fault features of its output line voltage in fault condition of power switch. On this ba-sis,the thesis puts forward the fault diagnosis method of power switch of TSMC based on the error voltageof switch group,and this method can judge switch group with fault and locate the fault switch of TSMC ac-cording to error voltage of switch group. The proposed method has many advantages,such as fast detec-tion,accurate diagnosis,high efficiency,etc. The simulation model and the experiment system of fault di-agnosis system of power switch are established and the results verify the validity and the feasibility of thefault diagnosis method mentioned above.
