    Abstract: The study describes the application technique of Fourier mathematical device for local transformation
in relation to the description of transient processes in the electrical circuits containing controlled rectifiers. It
was shown that this transformation allows to perform the transition from a variable structure system to a
permanent structure system of a discrete species using the example of a synchronous machine valve exciter.
The presented results of numerical calculations showed the discrete model adequacy.
