摘要

由于减少了器件电流应力和滤波器尺寸，交错拓扑结构在高功率、高电流应用中很受欢迎。尽管它很受欢迎，但在文献中缺乏一个适当的设计程序，用于CCM中工作的双向交错dc-dc变换器，包括选择适当的相位数和无源元件设计以优化变换器效率。本文介绍了一种用于大电流应用的双向交错降压/升压dc-dc变换器的综合设计过程。在变流器中使用碳化硅器件将进一步提高其效率和功率密度。

Bidirectional Interleaved Buck/Boost DC-DC Converter Design to Improve Power Density in High-Current Applications

Interleaved topologies are popular in high-power, high-current applications due to the reduction in device current stresses and filter sizes. Despite its popularity, a proper design procedure for bidirectional interleaved dc-dc converter operating in CCM including the selection of appropriate number of phases and passive component design to optimize converter efficiency is missing in the literature. This paper presents a comprehensive design procedure for a bidirectional interleaved buck/boost dc-dc converters for high-current applications. Use of silicon carbide devices in the converter will further improve its efficiency and power density.
