摘要

本文介绍了用3.3 kV SiC MOSFET模块设计和制造的高效两相交错DC-DC变换器。该转换器设计用于连接1.5 kV电池存储和800 V直流链路，但可以在其他类似配置中运行。实验验证了该系统的有效性，并在260 kW的额定功率下进行了测试，同时也实现了低功耗运行。结果表明，使用最先进的基于sic的功率模块可以达到高额定功率，以及显著的频率(20至25 kHz)和令人满意的效率，在标称功率下达到98.7%。此外，尽管相对较小的无源元件，交错操作导致高质量的输入和输出波形，因此，该系统可以与常见的IGBT解决方案竞争。

Two-phase interleaved DC-DC converter with 3.3 kV SiC MOSFET modules

This paper describes highly-efficient two-phase interleaved DC-DC converter designed and built with 3.3 kV SiC MOSFET modules. The converter is designed to connect 1.5 kV battery storage and the 800 V DC link but can operate in other similar configurations. The system is validated experimentally, and tested up to 260 kW rated power but also low power operation is presented. It is shown that the use of state-of-the-art SiC-based power modules allows to reach high power ratings, along with notable frequencies (20 to 25 kHz) and satisfying efficiencies, reaching 98.7% at nominal power. Moreover, interleaved operation leads to high quality of input and output waveforms despite relatively small passive components, Thus, the system can be competitively employed against common IGBT solutions.
