Opis:: Large-signal input characteristics of three DC–DC converter types: buck, boost and flyback working in the discontinuous conduction mode (DCM), obtained by precise large signal PSpice simulations, calculations based on averaged models and measurements are presented. The parasitic resistances of the converter components are included in the simulations. The specific features of the input characteristics in the DCM and the differences between the continuous conduction mode (CCM) and DCM are discussed.

Opis:: Ringing of an inductor current occurs in a DC-DC BUCK converter working in DCM when current falls to zero. The oscillations are the source of interferences and can have a significant influence on output voltage. This paper discusses the influence of the inductor current ringing on output voltage. It is proved through examples that the oscillations can change actual value of duty a cycle in a way that makes the output voltage difficult to predict.

Opis:: Small-signal transmittances: input-to-output and control-to-output of BUCK converter power stage working in CCM or DCM mode are discussed. Ideal converter case and converter with parasitic resistances are considered separately. Derivations of small-signal transmittances, based on different approaches to finding the converter averaged models, are presented and the results are compared. Apart from theoretical considerations, some results of numerical calculations are presented.

Opis:: Characteristic frequencies corresponding to poles and zeros of small-signal control-to-output transfer functions of popular DC-DC converters (BUCK and BOOST) are analyzed. The main attention is paid to influence of load conductance on the characteristic frequencies for converters working in continuous conduction mode (CCM) as well as in discontinuous conduction mode (DCM). Parasitic resistances of all converter components are included in calculations. In addition the improved description of CCMDCM boundary is presented. The calculations are verified experimentally and good consistency of the results is observed.
