| Abstract: | Aiming at the issue of fault prediction technique of power electronic circuits,a method based on characteristic parameter data and least squares support vector machine(LS-SVM) for the prediction of power electronic circuits was proposed.Taking the Buck converter circuit as an example,the fault prediction of power electronic circuits was achieved.Firstly,the output voltage was selected as monitoring signal,and then the average voltage and ripple voltage were extracted as characteristic parameters.Lastly LS-S... |
