Abstract

DC power distribution systems for data centers, industrial applications and residential areas are expected to provide higher efficiency, reliability and lower cost compared to ac systems. Accordingly they have been an important research topic in recent years. In these applications an efficient power factor correction rectifier, supplying a dc distribution bus from the conventional three-phase ac mains is typically required. This paper analyzes the three-phase buck-type unity power factor SWISS Rectifier showing that its input current THD can be improved significantly by interleaving. The dc output filter is implemented using a current compensated Integrated Common Mode Coupled Inductor which ensures equal current sharing between interleaved half bridges and provides common mode inductance. Based on the analysis an high efficient 8 kW, 4 kW dm-3 (64 Win-3) lab-scale prototype converter is designed using SiC MOSFETS. Measurements taken on a hardware prototype confirm a full power efficiency of 99.16 % and a peak efficiency of 99.26 %.
