A new distributed digital controller for the next generation of power electronics building blocks

The need for low-cost, high-reliability, modular, easy to use and maintain power electronics systems is fuelling the drive for standardized power electronics building blocks (PEBBs). Increased power density, user-friendly design, multifunctionality and increased reliability are the major issues that are being investigated. This paper proposes a new distributed digital control architecture for medium and high power PEBBs. The proposed architecture features high level of flexibility, modularity and paves the way towards future plug and play power converter systems.
