Interleaved DC/DC converters are an interesting solution in applications where stringent requirements on weight and volume are necessary. The interleaving technique allows reducing the weight of the total passive components by using parallel phases or channels. In this paper, the dynamic model of an Interleaved Boost DC/DC Converter (IBC) is developed via the Energy Factor (EF) and sub-sequential parameters. In a DC/DC converter, the EF relates the stored energy to its dynamic characteristics, which helps in the converter design. In addition, the developed model enables to study the dynamic behavior of the converter based on its efficiency, taking into account iron and switching losses that are not fully considered in the standard model. The EF model is compared to the switched model and standard average small-signal model in the MATLAB/Simulink environment in order to verify the modeling approach. As an example, a standard dual-loop control system is designed based on the developed models. Finally, an experimental validation has been performed to evaluate the impact of non-Ohmic losses on the converter dynamic.
