Preventive diagnosis of pulse power converter dynamics

For the pulse power converters, consideration was given to the preventive diagnosis of their anomalous modes caused by the nonlinear evolutionary processes of multiple period variations. Proposed was a variant of solution based on the symbolic models of periodic and transient processes generated by the geometric treatment of the invariants of the phase images. Developed was a procedure of continuous transformation of the time series enabling estimation of the direction of convergence of the transient process before its completion.
