The object of study is the sinusoidal voltage source that is composed of a PWM frequency converter with an output LC-filter and single-phase nonlinear output transformer. The mathematical description of nonlinear singularly perturbed system of differential equations for which the reduction has been performed. The nonlinearity is given to the form, which the synthesis control law using the method of Lyapunov functions will perform. The simulation results carried out within the limitations affecting the possibility of technical implementation of the resulting control law are presented. References 14, figures 6.
Key words: frequency converter, output LC-filter, one phase nonlinear transformer, singular perturbed system, Lyapunov functions method.
