Item Performance Analysis of Two Phase Interleaved Bidirectional DC-DC Converters for Electric Vehicle Application(Institute of Electrical and Electronics Engineers Inc., 2024) Mohurle, D.; Nagendrappa, H.Electric vehicles are gaining popularity due to their improved performance and low maintenance cost. Bidirectional DC-DC converters are employed in EVs since power management is critical. In regards to efficiency, voltage ripple, and current ripple reduction, an interleaved bidirectional DC-DC converter excels in the bidirectional DC-DC converter category. This paper investigates the performance of a two-phase interleaved bidirectional DC-DC converter with two topologies: i) parallel-input and parallel-output (PIPO), and ii) parallel-input and series-output (PISO) connection, for a fuel cell electric vehicle (FC-EV) system. Furthermore, comparative analyses of both topologies are examined. A thorough theoretical analysis of these converter topologies has been carried out. In step-up operation, a two-phase interleaved DC-DC converter with parallel-input and series-output connection (PISO) topology provides double the voltage gain and lower input current ripple at nearly the same duty cycle as an interleaved bidirectional DC-DC converter with parallel-input and parallel-output connection (PIPO) topology. In step-down mode, it also provides lower voltage gain and output current ripple. The results of extensive simulations performed in the MATLAB environment are presented. © 2024 IEEE.
