基于M-ary SVM的电力电子电路故障诊断方法研究

摘要

The fault diagnosis based on M-ray SVM is applied to the power electronic circuits. By means of the wavelet transforma-tion and Concordia transformation, the fault information from the power electronic circuit is extracted. When the circuit is diagnosed by using several typical fault diagnosis methods and the M-ary SVM method, the result shows that M-ary SVM method is effective and has higher accuracy and faster testing speed.%将基于M-ary 支持向量机的故障诊断方法应用到电力电子电路的故障诊断中。利用小波变换和Concordia变换提取电力电子电路故障信息,运用几种典型的故障诊断方法和M-ary SVM对电路进行诊断。实验结果表明,M-ary SVM可以有效地用于电力电子电路故障诊断中,具有高的故障诊断精度和更快的测试速度。
