摘要

双有源全桥（DAB）直流-直流转换器广泛应用于直流微电网和电力电子的各个领域。它具有高功率密度、易于实现软开关和双向功率传输能力等优点。传统的线性控制器难以满足日益增长的速度和鲁棒性要求。本文提出了一种基于布雷顿-莫瑟功率整形理论的控制策略，以改进 DAB DC-DC 转换器的控制策略。本文对 DAB DC-DC 转换器进行了建模，并根据 Brayton-Moser 功率整形理论设计了控制器。构建了 DAB DC-DC 转换器的仿真，并对不同工作条件下的 PI 控制、被动控制和功率整形 Brayton-Moser 控制三种控制策略进行了比较分析。

A power shaping based control strategy for dual active full-bridge converter

Dual active full-bridge (DAB) DC–DC converters are widely used in DC microgrids and various fields of power electronics. It has the advantages of high-power density, easy to implement soft switching and bi-directional power transfer capability. Conventional linear controllers have difficulty in meeting the increasing demands for speed and robustness. In this paper, a control strategy based on the Brayton–Moser theory of power shaping is proposed to improve the control strategy of DAB DC–DC converters. The DAB DC–DC converter is modelled and the controller is designed based on the Brayton–Moser power-shaping theory. A simulation of the DAB DC–DC converter is constructed and a comparative analysis is carried out for three control strategies of PI control, passive control and power-shaping Brayton–Moser control under different operating conditions.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
