包括不同电源和负载的配电系统（诸如电动车辆、飞行器配电系统和住宅微电网）需要新的功率转换架构。多端口转换器是传统多转换器系统的替代方案。本文研究了模块化多源桥（MMAB）变换器，它是一种基于有源桥和独立变压器连接的多端口变换器。该转换器是双向、完全模块化和可扩展的。它允许连接多个电源和可能改变其功率流方向的负载，允许模块的热连接和断开。每个端口中的功率流的控制取决于其它有源桥的控制脉冲之间的相对相移。开发了一种迭代算法并在数字设备中实现，以真实的实时控制转换器。在理论分析的基础上，对变换器的主要特性进行了实验验证。实验结果验证了理论预测。考虑到开环控制，模块之间的功率分配相对于期望值保持在9%的误差之下。
Electrical distribution systems comprising different power sources and loads, such as electric vehicles, aircraft electrical distribution systems, and residential microgrids, need new power conversion architectures. Multiport converters are an alternative to conventional multiconverter systems. This work studies a modular multiactive bridge (MMAB) converter, which is a multiport converter based on the connection of active bridges and independent transformers. The converter is bidirectional, fully modular, and scalable. It allows the connection of multiple power sources and loads that may change its power flow direction, allowing hot connection and disconnection of modules. The control of the power flow in each port depends on the relative phase shift among the control pulses of the other active bridges. An iterative algorithm is developed and implemented in a digital device to control the converter in real time. Besides theoretical analysis, the main characteristics of the converter have been validated in a lab prototype with five modules. The experimental results validate the theoretical predictions. Power distribution among the modules has been kept under 9% of error with respect to the desired value, considering an open-loop control.
