| Abstract |
This paper proposes a new approach to divide the total power between different legs in an interleavedbidirectional buck converter, based on the Fibonacci sequence. The paper revises the theoretical analysis of the interleaved buck converter, showing the current ripple analysis; a small signal analysis to find the plants, which represent the circuit, to further derive the control strategy; the validation of these plants via simulation; and the control strategy of the circuit, detailing the unbalanced current division. Finally, simulation results showing that the unbalanced power can be used in an interleaved buck configuration and still achieve zero output current ripple are presented. Discussions among the project adaptations for the interleaved legs, with emphasis for the power semiconductors, are also present in this paper. |
