The dual active bridge (DAB) converter has high efficiency and versatility; hence, such a converter has been used to design photovoltaic (PV) applications with both step-up and step-down voltage capabilities. However, PV systems require maximum power point tracking (MPPT) controllers to track the optimal operation conditions; moreover, PV voltage controllers are required to reject load perturbations that reduce the MPPT performance. This paper describes the operation of a DAB converter in PV systems and compares the performance of the DAB converter with a classical boost solution. In addition, this paper also presents a systematic analysis of the control techniques for DAB converters in PV applications, which provides useful information for selecting the most suitable approach for a particular application.

光伏应用中双有源桥式变换器控制技术的系统分析

双有源桥（DAB）转换器具有高效率和通用性；因此，这种转换器已被用于设计具有升压和降压能力的光伏 (PV) 应用。然而，光伏系统需要最大功率点跟踪 (MPPT) 控制器来跟踪最佳运行条件；此外，光伏电压控制器需要抑制降低 MPPT 性能的负载扰动。本文介绍了光伏系统中 DAB 转换器的操作，并将 DAB 转换器的性能与经典升压解决方案进行了比较。此外，本文还对光伏应用中 DAB 转换器的控制技术进行了系统分析，为选择最适合特定应用的方法提供了有用的信息。
