A new on-line fault diagnosis approach is presented for power electronic circuits. In general, waveforms from key points representing the operation state of a power electronic circuit are composed of segments of certain basic curves from a set. The mathematical formula of every basic curve of the set is called basic function. Further a segment of a basic function is able to be depicted by a feature vector. By means of the vector representation every original waveform is tramsformed into vector series...

A new on-line fault diagnosis approach is presented for power electronic circuits.

By means of the vector representation every original waveform is tramsformed into vector series which will further be transformed into a sentence. At last faults can be readily recognized by parse anlysis.

A program, which is made on the basis of the circuit model, should be input to the computer before computer-aided analysis and design can be made for the circuit. A thyristor is the main part of a power electronic circuit. Therefore, a thyristor model should be set up when computer-aided analysis and design is carried out for the power electronic circuit. However, many models are either too rough or too large that must be operated on a giant computer. Now consider that a thyristor can be regarded as the combination of two transistors. Normally, the transistor model can be found in any kind of universal circuit analysis program, by which a power electronic circuit containing thyristors can be analyzed with the aid of a personal computer.The main parameters of the model can be estimated easily according to those of thyristor. This paper gives a preliminary discussion on the calculating formula which is produced by Hu-Ki model. The model is simulated and analysed on IBM-PC and the calculated results are, on the whole, in good agreement with those of the experiment.

对电路进行计算机辅助分析和设计,其基础是根据电路元件的模型,编制程序输入计算机进行运算。晶闸管是功率电子电路中的主要器件,所以在进行功率电子电路的计算机辅助分析和设计时,必须建立晶闸管的模型。在众多的模型中,不是简单粗糙,就是网络太大,需要在大型计算机上计算。考虑到一个晶闸管可以看成由两个三极管组合而成,而一般通用电路分析程序都含有三极管模型,所以可用电路分析程序对含有晶闸管的功率电子电路进行计算机辅助分析,且可在PC机上进行。 模型的主要参数可根据晶闸管的主要参数求出,本文对Hu—Ki模型提出的计算公式进行了初步论证。利用得到的模型,在IBM—PC上进行仿真分析,结果与试验结果基本一致。
