Abstract :
Several sophisticated averaged-switch models have been proposed in the literature to represent the non-ideal pulse width modulated switched-inductor DC-DC converters based on the energy conservation principle. Alternatively, proposed is a full-order state-space averaged model that takes into account conduction losses associated with the switching cell´s components and is seamlessly functional in all operational modes. The proposed model also demonstrates improvement in accuracy compared to several established models
