%X 随着可再生能源和直流微网发展&#65292;双有源桥电路成为研究热点&#65292;精确移相控制对其至关重要。传统单移相控制轻载性能差&#65292;双移相和三重移相控制算法复杂、适应性弱&#65292;现有方法均存在不足。为此&#65292;本文提出基于双有源桥电路移相控制配置和内移相中心对称叠加补偿方法的方案。该方案通过ePWM模块的配置、外移相角动态生成、内移相自适应配置及前馈量对称补偿抑制电流畸变。文中详细阐述了双有源桥电路拓扑、ePWM模块配置、外移相信号配置器设计、内移相配置及补偿算法原理。仿真实验表明&#65292;该方案能实现高低压侧高效双向能量传输&#65292;满足不同场景移相控制需求。内移相中心对称叠加补偿方法可实时补偿移相角误差&#65292;提升系统稳定性、响应速度和控制精度。且该技术有望扩展应用于双通道、多通道及其他类型的双有源桥电路&#65292;从而最大限度地提高电路效率以优化系统性能。<br>With the development of renewable energy and DC microgrids, dual active bridge circuits have become a research hotspot, and precise phase shift control is crucial for them. Traditional single phase shifting control has poor light load performance, and dual phase shifting and triple phase shifting control algorithms are complex and have weak adaptability. Existing methods all have shortcomings. Therefore, this article proposes a scheme based on dual active bridge circuit phase shift control configuration and internal phase shift center symmetric superposition compensation method. This scheme suppresses current distortion through the configuration of ePWM module, dynamic generation of external phase angle, adaptive configuration of internal phase shift, and symmetrical compensation of feedforward. The article provides a detailed explanation of the dual active bridge circuit topology, ePWM module configuration, external phase shift signal configurator design, internal phase shift configuration, and compensation algorithm principles. Simulation experiments show that this scheme can achieve efficient bidirectional energy transmission on the high and low voltage sides, meeting the requirements of phase shifting control in different scenarios. The symmetrical superposition compensation method with internal phase shift center can compensate for phase shift angle errors in real time, improving system stability, response speed, and control accuracy. And this technology is expected to be extended to dual channel, multi-channel, and other types of dual active bridge circuits, thereby maximizing circuit efficiency to optimize system performance.
