多端口电源转换器在包括电池管理系统、数据中心电力输送和可再生能源系统在内的广泛应用中是必需的。这些系统包括许多具有复杂和双向功率流的分布式和模块化功率转换单元。本文系统地研究了具有大量端口的多端口功率转换器的体系结构、建模和控制，并探讨了新兴的“功率FPGA”概念的理论基础-灵活、可编程、粒度和自适应的功率电子器件-这将使广泛的令人兴奋的应用成为可能。我们将多端口功率变换器分为两大类，并开发了一个基于牛顿-拉夫森方法的软件工具，以快速识别控制策略。我们分析了这种控制框架的适用性和局限性，并模拟了一个100端口的能量转换器与可编程的功率流。四端口可编程能量转换器的建立和测试，实验验证所提出的建模和控制策略。
Multiport power converters are needed in a wide range of applications including battery management systems, data center power delivery, and renewable energy systems. These systems comprise numerous distributed and modular power conversion cells with sophisticated and bidirectional power flow. This paper systematically investigates the architecture, modeling and control of multiport power converters with a large number of ports, and explores the theoretical foundation of an emerging “Power FPGA” concept - Flexible, Programmable, Granular and Adaptive power electronics - that will enable a wide range of exciting applications. We classified multiport power converters into two major categories, and developed a software tool based on Newton-Raphson method to rapidly identify the control strategy. We analyzed the applicability and limitations of this control framework, and simulated a 100-port energy converter with programmable power flow. A four-port programmable energy converter is built and tested to experimentally validate the proposed modeling and control strategy.
