摘　　要：研究了有源滤波器APF的起动与运行时的直流侧电压稳定两个实用化关键技术。分析了起动过程中和IGBT的死区对直流侧电压稳定的影响问题。提出了一种改进的起动方式和通过判断IGBT桥臂电流的方式设计死区的解决方案。最后用仿真软件PSCAD/EMTDC和搭建实验平台做了仿真实验验证,证明了所提方案的合理性,为APF实用化进一步的研究提供帮助。Study was made on two practical key technologies for DC side voltage stability of start and operation of active power filter. Analysis was made on the problem of voltage stability at DC side affected by IGBT＇s dead zone during starting process. An improved starting method was raised, the solution of dead zone designed via judging IGBT＇s bridge arm current. At last with simulation software, PSCAD/ EMTDC simulation experiment proves that the raised solution is reasonable so as to provide help for further study of APF.
