This work contains the results of the research carried out on the framework of the design of the resonant power module of DAB. The peculiarity of this device is that it is supposed to be used as part of the basic element of a scalable power storage system, the load of which is an industrial three-phase network. The paper proposes a method of designing such devices based on preliminary analytical calculations and the development of numerical models. This method includes three stages. In the first iteration, the parameters of the resonant CLLC converter. In the second iteration, in the course of performing more accurate calculations and development of numerical models, the output parameters and the adjustment characteristic of the converter are determined, taking into account the specifics of the load. At the third stage, a numerical model of a high-frequency transformer is developed to determine the number of losses in the core and estimate the values of magnetic induction.
