Annotation: The paper presents the research results of the nonlinear phenomena causing possible dynamic modes of one of perspective structures of semi-conductor converters with dispensing of energy, which is transferred in loading. For the first time there are analyzed the revealed steady periodic, quasi periodic and chaotic fluctuations of voltage and currents of the inverting converter, their area of existence and bifurcation borders of the calculated variety of dynamic modes. The numerical-analytical method of the analysis of key converters provides the reliability of calculations for long numerical series, in case of either continuous or breaking currents of the inductive store of energy.

Keywords: bifurcation, design mode, stability areas, border of dynamic modes, dynamic chaos
