三有源桥式DC/DC转换器通过控制分布式电力系统和负载之间的潮流，为微电网的实现做出了贡献。该TAB转换器的控制系统具有2输入2输出的多输入多输出结构和强非线性的特点。在解耦器的精度和控制器结构的简单性之间存在一个权衡的问题。因此，本文提出了一种新的控制方法，使解耦器在保持控制器结构简单的同时，能够在较宽的范围内工作。为了验证理论的正确性，文中还给出了1kW原型TAB变流器的实验结果。结果，证实了所提出的控制器抑制了干扰。
Triple Active Bridge (TAB) DC/DC converter contributes to the realization of micro grid by controlling the power flow among distributed power systems and load. The control system of the TAB converter has characteristics of a 2-input 2-output MIMO structure and strong nonlinearity. There is a trade-off problem between the accuracy of the decoupler and the simplicity of the controller structure. Hence, this paper proposes the new control method that enables the decoupler to operate in a wide range while keeping the simplicity of the controller structure. Also, this paper describes experimental results of 1 kW prototype TAB converter in order to verify the validity of the theoretical considerations. As a result, it was confirmed that the interference is suppressed by the proposed controller.
