Contents I. Introduction
The continuous growth of renewable energy sources and the ever-increasing demand for efficient energy conversion systems have propelled the development of advanced power electronic systems [1]. One of the outcomes of this technological evolution is the emergence of flexible DC grids, which have come to be seen as a linchpin in the modern power architecture due to their potential for seamless energy flow control and efficient power conversion. DAB converters have gained substantial traction in this arena. Figure 1 provides a visual representation of a standard DAB converter. Their inherent ability to manage bidirectional power flow and operate over a wide voltage range has made them indispensable in the domain of flexible DC grids [2]. However, the complexities of integrating various energy sources and the incessant demand for high efficiency and reliability necessitate further research into optimizing their topologies and control methodologies.
