摘　　要：大功率DC/DC变换器中交错并联技术被广泛使用。为了减小变换器的体积,将耦合电感引入大功率DC/DC变换器。首先介绍了相关理论,其次给出了耦合电感的设计步骤和公式,最后给出了有限元分析(finite element analysis,FEA)仿真数据。将耦合电感和传统的单路分立电感进行了比较。仿真结果表明,给出的设计方法可行,可以大大减小变换器的体积。Multichannel interleaving techniques have been used widely in high power DC/DC converters. This paper proposes coupling inductor application in high power DC/DC converter in purpose of size reduction. The theories, design processes,design formula,FEA simulation and comparison with coupling and discrete inductor are introduced in the paper. Simulation results verify this degin method, and coupling inductor can reduce the size of the converter greatly.
