چکیده
Bidirectional converters play a major role in energy transfer by facilitating the flow of power between sources and consumers. Among isolated bidirectional converters, the DAB converters hold a special place. The features of DAB converters include electrical isolation for high safety margins, high efficiency for different voltage gains, leakage current reduction, higher power transfer capacity, modular and symmetrical structure, ZVS, and overall high performance. Employing precise modeling techniques and advanced control methods, the DAB converters can obviously improve power transfer efficiency, reduce energy losses, and prolong the service life of electrical equipment. This paper is focused on DAB converters modeling, including parasitic elements and their influence on the modeling accuracy. Furthermore, a proportional-integral controller is designed with the purpose of dynamic performance and system stability improvement. The accuracy of the model and theoretical analyses has been validated through simulation results. The proposed model of the digitally controlled DAB converter is capable of accurately predicting the boundaries of stability, hence effectively ensuring the stable operation of the converter.کلیدواژه ها
