Forecasting of PWM-regulator dynamics

PWM energy converters (PEC) are rich in nonlinear dynamics. Thereupon in practical application increase of PEC efficiency is hold in the restrictions stipulated by nonlinear phenomena presence. A variant of this contradiction resolve seems to be in calling of the methods of PEC dynamics forecasting which allow applying of necessary control actions before abnormal process appearance. Fundamental problems of abnormal process forecasting are considered in the paper. Variants of problem solutions are analyzed within the bounds of the fractal method. Perspective ways of development are marked on the basis of this analysis results.
