| Modeling of power electronic converters plays a significant role in examining the behaviour and designing control systems. Dual Active Bridge (DAB) converters, due to many advantages such as inherent soft-switching, bidirectional power transfer, and higher energy density, are used in various applications such as SST transformers, smart grids, and electric vehicle battery chargers. In this paper, a new reduced-order model for a DAB converter is introduced by modeling nonlinear elements such as semiconductor devices and transformers. By considering all power loss elements, and input/output filters, the modeling becomes more realistic. The performance and accuracy of the proposed model is improved compared to conventional reduced-order methods. Small signal modeling for the DAB converter is curried out and control transfer functions of the system are investigated. Additionally, frequency response analysis of the proposed model under different conditions is compared with the detailed model of the DAB converter containing nonlinear elements implemented in PLECS software. Simulation results demonstrate a satisfactory accuracy of the proposed model in assessing the performance and dynamic behavior of the DAB converter under various operating conditions. | ||
