On indeterminate modes of functioning of a voltage stabilizer with pulse-width modulation

With a voltage stabilizer with pulse-width adjustment taken as an a example, an attempt has been made to explain why indeterminate signals are arising. A mathematical model of a stabilizer and methods of looking for stationary solutions have been developed. This has resulted in the explanation of the mechanism of arising indeterminate signals in the stabilizer. The authors regard it possible to extrapolate the reasons for the arising of indeterminate signals to any dynamic systems (in particular, turbulent effect in hydrodynamics, fibrillation of a miocard in cardeology etc.). This extrapolation is based upon the analysis of numerous experimental data on the dynamics of various entities.
