Modified Bi-directional DC-DC converter For EVs

This paper introduces a modified bidirectional DC-DC converter with equal current sharing capacity with 4 times the input voltage. This propose circuit has an excellent conversion ratio for use with electric car applications. The proposed system’s capacitive voltage-divider stage provides minimal stress across the switches, allowing the designer to use small resistance. The alternative arrangement of switches increases power density while significantly reducing current ripple and filter sizing. Two phases are described here, interleaved to construct the equal current sharing phenomena. This connection of converter is thoroughly examined, and its characteristics are studied and compared to those of other state-of-the-art bidirectional converters.
