摘　　要：针对APF(有源电力滤波器)逆变器中IGBT在长期运行时容易出现故障的情况,提出一种基于DSP软件检测定位IGBT故障的方法以及APF容错拓扑结构。分析了IGBT开路故障诊断算法,提出了通过DSP软件程序实现故障诊断的方法,同时给出APF容错拓扑结构以及容错控制实施方法,在Matlab/Simulink仿真平台建立相应的APF控制系统仿真模型,通过仿真实验验证了该控制方案的可行性。For the IGBT （ Insulated Gate Bipolar Transisto） of active power filter is prone to failure which may re- sult in serious consequences, an idea of detecting and locating the breakdown of IGBT on basis of DSP software and a fault tolerant topology of redundant single bridge arm of active power filter are proposed in this paper. Fol- lowing the analysis of the algorithm of fault diagnosis of open circuit, a fault tolerant topology of active power filter and a specific implement method of fault-tolerant control are provided. Meanwhile, a related simulation model of the control system of active power filter is established on the MATLAB/Simulink simulation platform where the feasibility of this control scheme is verified through simulation experiments.
