Distributed, modular, open control architecture for power conversion systems

Due to close coupling to hardware and lack of software engineering technologies, the control software in digitally controlled power conversion systems is difficult to design and maintain. This is a natural consequence of a topology- or application-driven design approach. This paper proposes a distributed, modular, open control architecture for power conversion systems to decompose control design complexity and encapsulate and localize design dependencies to reduce unnecessary redesign effort and improve software quality. An implementation of the proposed control architecture is presented and evaluated by comparison to the legacy approach to control design in industry and academia.
