Abstract

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.
