Zusammenfassung:	In this work, a new performance parameter, namely power factor, introduced is used in the analysis of buck DC-DC converter operating in DCM. The power factor concept is now applied in the analysis of DC circuits. The derivation of the parameter and its application as one of the performance parameters in the analysis of the buck DC-DC converter operating in DCM and boost converter operating in discontinuous mode (DCM) has been carried out considering all the parasitic elements of the circuit. All the equations are normalized and expressed in terms of power factor so that a user can easily study the influence of the circuit elements on the performance of the converter. This will aid the designer to plot design curves for any loading conditions and choose the factor ldquoKrdquo, which is used to calculate the inductance required to operate the converter in a desired mode.
