摘要

收起

电路结构简单且易于控制的典型隔离型双有源桥DAB（dual-active-bridge）变换器，在需要能量双向流动的场合被广泛应用。因此，研究如何提高变换器的工作效率尤为重要。首先，对比分析国内外学者提出的效率优化策略，发现基于移相控制的优化方法中两侧桥内移相角和桥间移相角具有很强的相关性，造成变换器工作特性分析困难。然后，基于扩展移相EPS（extended-phase-shift）控制对变换器的整流平均电流进行优化，定义新的移相角，分析新移相角下变换器的传输功率和平均电流。最后，搭建Simulink仿真和实验平台进行验证。

Abstract

收起

The typical isolated dual-active bridge (DAB) converter with a simple circuit structure and easy control is widely applied under scenarios where the bidirectional energy flow is required. Therefore, it is particularly important to study how to improve the working efficiency of the converter. First, the efficiency optimization strategies proposed by domestic and foreign scholars are compared and analyzed, and it is found that the intra- and inter-bridge phase shift angles on two sides have a strong correlation, which causes the difficulty in analyzing the working characteristics of the converter. Second, the rectified average current of the converter based on extended-phase-shift (EPS) control is optimized, a new phase shift angle is defined, and the transmission power and average current of the converter under the new phase shift angle are analyzed. Finally, a simulation platform based on Simulink and an experimental platform were set up for verification.

Key words
