摘要

本文提出了一种双向3X dc-dc乘法器/分法器，它可以将电池与逆变器直流母线连接起来，用于混合动力电动汽车(HEV)牵引驱动。与传统的多级dc-dc变换器相比，该变换器具有三种输出/输入电压比，且转换平稳。本文提出了一种限制暂态涌流的控制方法，以及一种用于多级dc-dc变换器的新型再生箝位电路。通过利用寄生电感或最小电感从一个空芯电感，变换器的尺寸和重量可以显着减少。它的无磁特性和高效率为未来宽禁带器件的高温工作提供了潜力。实验结果验证了该拓扑的工作原理和设计思想。

3X DC-DC Multiplier/Divider for HEV Systems

This paper presents a bidirectional 3X dc-dc multiplier/divider that can interface the battery with the inverter dc bus for hybrid electric vehicle (HEV) traction drives. Compared with traditional multi-level dc-dc converter, this converter can have three output/input voltage ratios with smooth transition. The control method to limit the transient inrush current, as well as a novel regenerative clamping circuit for multi-level dc-dc converters is provided in this paper. By utilizing the parasitic inductance or the minimum inductance from an air core inductor, the size and weight of the converter can be significantly reduced. Its magnetic-less feature and high efficiency provide the potential of the high temperature operation with the future wide bandgap devices. Experimental results are given to verify the operating principle and the design concepts of this topology.
