本文展示了一个高功率双向DC-DC转换器的性能评估和实际演示,功率密度为20 kW/l,使用1200 V/100 A的SiC MOSFET模块从CREE。该转换器是基于一个双交错的硬开关拓扑工作在75 kHz。为了提高功率密度,使用水冷磁性元件。一个60千瓦的转换器的实验结果表明,在这种应用程序中的工作频率增加到100 kHz以上的潜力。
This paper shows the performance evaluation and practical demonstration of a high-power bi-directional DC-DC converter with a power density of 20 kW/l, using 1200V/100A SiC MOSFET modules from CREE. The converter is based on a dual-interleaved topology with hard-switching operating at 75 kHz. To increase the power density, water-cooled magnetic components are used. The experimental results of a 60 kW converter show the potential to increase the operating frequencies up to 100 kHz and beyond in this application.
