MultiAnalyser for Very High Voltages

Currently, inverters mostly feed into the low-voltage grid. They are then coupled to the medium-voltage grid via large 50 Hz transformers. The use of new types of silicon carbide (SiC) transistors with very high blocking voltages now also makes it possible to connect the inverters directly to the medium-voltage grid.
