Researchers at the Fraunhofer Institute for Solar Energy Systems ISE developed and successfully put into operation an inverter for direct feed-in to the 10 kV medium-voltage grid. The inverter contains high-voltage silicon carbide (SiC) transistors which allow for coupling to the medium voltage grid without requiring an additional transformer. The three-phase inverter can be used to regulate reactive power as well as to actively filter undesirable harmonics in the electricity grid. Thus, it actively contributes to the stabilization of future power grids with a large share of renewables.
