摘要

它的优点是在最少的转换步骤内收获和调度功率。本文提出了一种单级多输入多输出转换器(MIMOC),它可以在未来的智能家居中使用直流配电架构连接各种能源和负载。所提出的MIMOC具有结构紧凑、集中控制、电流隔离、宽电压转换比和精确电压调节等优点。分析了所提出的MIMOC的工作原理。提出了一种特殊的开关模式,并提出了一种基于多变量PI的控制方案,该方案除了可以调节多个输出电压外,还可以对来自不同电源的输入功率进行预算。提供了开关模型和平均模型来验证所提出的MIMOC的运行。

A flyback converter with multiple ports for power management in DC distribution systems
It is of advantage to harvest and dispatch power within a minimal number of conversion steps. This paper proposes a single-stage multi-input multi-output converter (MIMOC), which can be used for interfacing diverse energy sources and loads in future smart homes with dc power distribution architectures. The proposed MIMOC offers compact structure, centralized control, galvanic isolation, and wide voltage conversion ratio with precise voltage regulation. The operation principle of the proposed MIMOC is analyzed. A specific switching pattern is proposed, and a multivariable PI based control scheme is presented that enables budgeting the input powers coming from different sources in addition to regulating several output voltages. Both switch and average models are provided to validate the operation of the proposed MIMOC.
