The present invention is concerned with a three-level power electronic converter circuit topology with a first, lower frequency stage including a larger number of lower frequency switches and with a second, higher frequency stage including a smaller number of higher frequency switches. Only the higher frequency switches are realized or implemented by fast switching, wide bandgap semiconductors while the lower frequency switches are realized by conventional silicon based semiconductor switches, resulting in a split frequency converter circuit with an optimized use of, and investment in, fast switching semiconductors. The proposed power converter solution is well-suited for grid-connected inverter applications aiming for high power density.

This application concerns a magnet having a magnet body as well as a method for manufacturing such a magnet. The magnet body has a first region with first magnetic properties and a second region with second magnetic properties that are different to the first properties. Owing to the manufacturing process of the magnet body, the relative location of the first region and the second region within the magnet body is freely predeterminable.

The present invention is concerned with a flexible way of operating a wind farm with a plurality of degrading wind turbine components. According to the invention, maintenance scheduling and power production in the wind farm are handled concurrently in a single optimization step. Instead of a serial approach first scheduling maintenance activities and subsequently adapting the power production and/or wind turbine operation the two aspects are optimized together. The wind farm operation takes maintenance aspects into account by adapting a life index or health status based on modeled mechanical and electrical stress. Accordingly, the wind farm owner may decide when and how much energy to produce accepting which level of stress to the turbine equipment. The proposed optimization of wind farm operation includes all aspects of transmission network operator settings, the topology of wind farms and the underlying collector grid, the short and long term wind conditions forecasts, the conditions of the turbines, the estimated remaining operational time under different usage patterns and times, as well as aspects of the electricity market.
