摘要多电平逆变器已经广泛应用于高压大功率场合,因此关于这类电路的故障诊断也变得越来越重要。本文研究了三电平逆变器单个器件开路故障的诊断问题。根据调制电压和对应相电流的方向,把电路分成四个工作区间。当器件在不同工作区间开路时,对桥臂电压波形进行详细的实时分析,并提出三条故障判断依据。设计具体的故障诊断电路,根据桥臂电压波形的电平及其持续时间的变化实现器件开路故障的自动诊断。实验结果表明,该方法能够快速区分提出的故障模式,并精确定位到故障器件。

Abstract：Multilevel inverters have widely applied in high-voltage and high-power applications. Therefore, fault diagnosis of such circuits is becoming more and more important. Diagnosis of single device open circuit fault for a three-level inverter is discussed in this paper. According to direction of the modulation voltage and corresponding phase current, working period of the inverter is divided into four working ranges. When the fault of device open circuit occurrs in different working range, the bridge voltage is analyzed in detail and three fault diagnosis criterions is proposed. Based on the bridge voltage level and its duration, a kind of circuit is designed to achieve automatic diagnosis for device open circuit fault. The experimental result shows that the method can isolate fault patterns proposed exactly and quickly.

Key words： Three-level inverter fault diagnosis bridge voltage real-time waveform analysis
