摘要
首先建立三相电压型PWM逆变器的键合图模型,在键合图模型的基础上,采用故障树分析法,针对逆变器功率管的开路故障,进行了定性故障诊断方法的研究。通过分析验证,该方法具有对模型精度要求低及计算量简单等优点。
The bond graph model of three-phase voltage PWM inverter was established and based on it,open-circuit fault of the transistor in inverter was qualitatively analyzed with fault tree analysis method.Analytical results prove advantages of this method of low accuracy requirements and easy calculation.
