  • Abstract
    The paper presents a high-efficiency grid-connected 10 kVA AC/DC converter and its experimental verification during various operation modes. The converter was designed to operate with a natural convection cooling, which is possible due to performance of a three-phase SiC MOSFET module (1200V/50A) switching at 16 kHz. Moreover, a LCL filter is built with the inductors also optimized regarding low power losses. The AC/DC converter was investigated in active rectifier and grid-inverter mode with special focus on efficiency measurements. Typically, total losses are slightly above 1% of the nominal power but in specific operation areas, such as an active rectifier mode, efficiency higher than 99% was observed.
