One of the key enabling technologies behind many global megatrends, which are a ecting our lives as individuals and as a society in many different areas, is power electronics. Prominent examples are the shift from conventional energy sources to renewable energy sources, the reduction of greenhouse gas emissions due to the electri cation of mobility, and the trend towards cloud-computing in the information technology area, which are all based on the development of cost-e ective, e cient and compact power electronic systems. In order to ful ll future requirements for power electronic systems, it is therefore of great importance to identify new ways to develop systems with higher e ciency, power density, and reliability.
The analysis of relevant literature reveals, that improvements of power electronic systems are to a great extent either based on the improvements of speci c components or on the modi cation of known control algorithms and/or topologies. These improvement processes, however, are of evolutionary nature and are not going to provide significant steps of performance improvements compared to today's solutions for the foreseeable future.
