摘　　要：换相失败是串级调速系统逆变器的常见故障,与许多因素有关。分析了串级调速系统换相失败的原因及其影响因素,并针对电源故障引起的换相失败,提出了控制方法,运用MATLAB/simulink对该方法进行仿真研究。结果表明该方法是准确的、可行的,便于工程上的应用研究。Commutation failure, one ofthe most common faults in the inverter ofcascade control system, isrelated to many factors. Based on the analysis of commutation failure for chopping cascade speed regulation system, the measures against commutation failure are given for power fault, The simulation of the dynamic model on MATLAB/ simulink was introduced, the result of the simulation illustrated that the measures was accurate and feasible.
