“…It consists of introducing an additional parallel resistance with the aim of appropriately accounting for inductor losses due to current ripple phenomenon. Thus, an improved averaged model is achieved compared to that proposed in [8]. It enables very good estimations of both inductor current ripple and averaged power losses.…”

“…Such approximations significantly ease the achievement of averaged models, but prevent accurate estimations of current and voltage evolutions, as well as the accomplishment of sound power losses and efficiency analysis [3]- [8]. In this context, inductor current ripple is almost always neglected, leading to mismatches in averaged inductor current and power losses estimations, especially when relatively low switching frequency is employed [9]- [10].…”

An inductor modeling suitable for DC-DC converters is proposed in this paper. It consists of introducing an appropriate parallel resistance in order to account for inductor current ripple when averaging technique is employed. This allows the development of an improved averaged model for DC-DC converters, which takes into account inductor power losses due to current ripple phenomenon. 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.
