Inside the Solid State Transformers
Solid State Transformers technology continues to excite researchers in academia and industry. Despite many promises of power-dense high-performance conversion, there are significant challenges encountered in the practical design of these highly modular, galvanically isolated power electronics converters. These stem from high power and high voltage aspects of design, insulation coordination, high voltage magnetic components, thermal aspects, and the complexity of controller hardware and control algorithms. High modularity strongly impacts the reliability and availability of the SST as a whole and has a strong impact on the scalability in terms of voltage, current, and power ratings. Redundancy in design is often adopted, further complicating the realizations of power stages.
The tutorial will systematically address numerous technological aspects inside the MW-level SST design, present commonly used technologies, as well as some first-hand experiences and solutions used or developed at the Power Electronics Laboratory at EPFL, by the instructors. When appropriate, PLECS models and simulations will be used to support the introduced concepts and methods to the audience.
