Opis:: Small-signal input characteristics of BUCK and BOOST DC-DC power converters in continuous conduction and discontinuous conduction mode have been presented. Special attention is paid to characteristics in discontinuous conduction mode. The input characteristics are derived from the general form of averaged models of converters. The frequency dependence of input admittance and other input characteristics has been observed in a relatively low-frequency range. The analytical formulas derived in the paper are illustrated by numerical calculations and verified by experiments with a laboratory model of BOOST converter. A satisfying level of conformity of calculations and measurements has been obtained.

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.
