Abstract—The legacy approaches to control development of power conversion systems is topology or application oriented. Due to close coupling to hardware and lack of software engineering technologies, the control software in digitally controlled power conversion system is difficult to design and maintain. This paper proposes a distributed, modular, open control architecture for power conversion systems is proposed to decompose control design complexity and encapsulate and localize independent varieties to reduce unnecessary redesign effort and improve software quality. An implementation of the proposed control architecture will also be presented and evaluated by comparison to the legacy approach to control design in industry and academic. I
