An average modeling approach for DC-DC power converters is presented in this paper. It allows the achievement of accurate averaged models of DC-DC converters, which account for dynamic and steady state operations, over both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). In particular, appropriate equivalent switching signals are introduced in order to account for each converter operating state. In addition, a suitable inductor model is introduced in order to improve inductor losses estimation. As a result, the proposed averaged modeling enables an enhanced power losses estimation by accounting for switching and current ripple phenomena. The worth and effectiveness of the proposed modeling approach has been validated through a simulation study, which is performed in the Matlab-Simulink environment and refers to the case of a boost DC-DC converter.
