A wide-bandgap based Power Electronic Building Block for reliable modular power converter

Modern industry is struggling with constantly shortening “time to market”, as usage of power electronics is rapidly increasing in recent years - from increasing interest in electrical vehicles, through new investments into renewable energy sources up to industrial applications of power electronics equipment: e.g. automotive chargers, UPSs, motor drives etc. Thus, either scientific and industrial community intensifies research in decreasing the engineering effort required for development of new power converters. One of possible solution s is usage of Power Electronic Building Block (PEBB), which can be further utilized to develop small- and middle-scale power conversion systems. The main assumption behind the PEBB concept is to build a generally available, simple and efficient standard for hardware construction, so that the burden of work on the converter is directed more towards new control methods and optimization of the current ones. Step by step, the design process is covered in this paper.
