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.
