Abstract
This paper presents the operation of a DC-DC converter for bidirectional power transfer with battery energy storage system. The converter topology under study resolves the existing disadvantages of conventional buck - boost bidirectional converter and provides benefits in terms of reduced size with higher efficiency and lower input source ripple current. The performance of non-isolated 4-phase interleaved buck-boost bidirectional converter has been studied using MATLAB simulations. In order to get a better insight, this paper proposes a control method that takes the interaction of 4phase currents into account. In boost mode operation, battery is getting discharged while it maintains the DC bus voltage. In buck mode operation, battery is getting charged at constant current. The design of non-isolated four-phase interleaved bidirectional converter of 150 kW with simulation results are presented to validate the design and performance of the converter. © 2023 IEEE.
