This paper presents a grid-connected 10 kVA AC/DC converter built with 25mΩ SiC MOSFETs. The converter design process was based on an optimization procedure, which was applied to find the parameters that provide efficiency of 98.5% and power density of 3 kWA/dm3. The 10 kVA prototype, including LCL filter, was built and tested in various operation modes showing very good performance and high efficiency. The AC/DC converter is also able to act as an active power filter compensating high-order harmonics of the grid current caused by diode rectifier.
