软件定义的电力电子：功率模块的互连与协同

This article proposes a concept of software-defined power electronics (SWD-PE) to abstract the design and development of power electronics systems. Key motivations of SWD-PE include standardizing the design procedures of key energy conversion components and abstractly generalizing the power electronic system to fit different types of electrified load/source applications. The proposed SWD-PE architecture is composed of three layers: 1) application function layer for open access of different electrified load/source interfaces and the corresponding control function library; 2) interconnection layer for the high level coordination and management of the power electronics system; and 3) physical layer for the desired type/number of standardized power modules equipped with current-/voltage-source local controller. The proposed SWD-PE architecture is mainly featured with three merits: 1) generalized design procedures to reduce the repetitive power electronics design processes; 2) reconfigurable architecture to form different power converter topologies with the corresponding control functions; and 3) wide application interfaces to be applicable for various types of electrified load/source. Compared to the previous work, the proposed SWD-PE achieves more generalized power electronic design procedures with more robust energy conversion control performance.
