本文介绍了一种用于交通电力电子系统的100 kW SiC开关储能变流器。该双向DC-DC转换器的目标电压转换为300-600 V。提出了半导体总损耗指数来评价拓扑结构和器件技术。利用该指标对Boost变换器和单节STC进行了比较。STC的设计程序，包括SiC管，散热器，谐振槽组件，和直流电容器，详细说明。给出了一台100 kW单电池STC工作在零电流开关模式下的仿真结果。一个100千瓦的第一代硬件原型使用1200 V，600 A的SiC功率模块已经建成和测试。主回路的功率密度约为42 kW/L。实验结果表明，该硬件样机具有良好的热性能，与理论设计相一致。测量的效率在30 kW左右达到峰值98.7%，在50 kW时达到峰值98.5%，在100 kW满负荷时达到峰值97.4%。
This article presents a 100-kW switched tank converter (STC) using SiC mosfets for transportation power electronic systems. This bidirectional dc–dc converter targets 300–600 V voltage conversion. Total semiconductor loss index has been proposed to evaluate topology and device technologies. The boost converter and one-cell STC have been fairly compared by utilizing this index. The STC design procedures, including SiC mosfet, heat sink, resonant tank components, and dc capacitors, are explained in detail. The simulation results of a 100-kW one-cell STC working at zero-current switching mode have been provided. A 100-kW first-generation hardware prototype using 1200 V, 600 A SiC power module has been built and tested. The power density of the main circuit is about 42 kW/L. The desirable thermal performance of the hardware prototype is demonstrated, which is consistent with the theoretical design. The measured efficiency reaches peak 98.7% at around 30 kW, about 98.5% at 50 kW, and 97.4% at 100 kW full load.
