Title: A Semi-modular and SiC-based Smart Transformer


In the lecture, the concept of a Smart Transformer (ST) Demonstrator is presented. This hardware prototype, developed at Chair of Power Electronics of Kiel University, demonstrates the high potential of such systems, as well as the high performance of the architecture proposed by the research group. The architecture is based on the modular concept using a specific topology, providing high performance and economic advantages. Thus, it is very appealing for industry application. Among the several advantages, the easy maintenance is highlighted. The ST Demonstrator is a three-phase system and it connects a low voltage dc with value of 800V and a medium voltage ac with output voltage level of 2.6 kV line-to-line. Moreover, the system can process up to 100 kW of output power.

  • Our research is focused on the design of high efficient and reliable PWM-based power converter architectures (single-cell, multi-cell, multilevel), their modelling and control to exploit commercial as well as new power semiconductor devices with minimum over design.
    We develop controllers for electric drives and we are particularly skilled in the integration of renewable energy systems into the electric grid.
