A study of modeling and simulation for soft-switched bi-directional DC-DC converters

In this paper, an extended averaged model is developed for a soft-switched bi-directional DC-DC converter for high-power applications. The proposed technique can be applied to any DC-DC converter with a high-frequency isolation transformer. Simulation results of Matlab/Simulink using the proposed average model are compared to those of detailed circuit simulation to verify the validity of this technique.
