2.1 Block Diagram

This reference design is composed of the following boards:

  • Medium voltage board composed of an AC/DC and a part of DAB Converter (2 H-Bridges).
  • Low voltage board composed of the second part of the DAB Converter (1 H-Bridge).
  • Two control card boards (TMDSCNCD28P65X) used for the MV Board and the LV Board.
  • Six gate drivers boards used to control and protect the power FETs.

Figure 2-1 shows a schematic representation of the 50kW SiC-based modular solid-state transformer.
