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 DCDC 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.

Abstract
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 DCDC 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.
