Control and Study of the Bidirectional Three Phase DAB Converter

This research consists on the study and control of the bidirectional 3-ph high frequency double active bridge (Bi-3φDAB) DC/DC converter. The sort of these converters is utilized in renewable energy system, also it is appropriate for some applications such as the automotive and avionic applications. This last comprises of two power stages which are isolated whereby three 1-ph high frequency transformers in expect to offer an insulation betwixt the two ports. To manage the power transmission between the two terminals, a phase shift angle is presented between the two power stages. This system features a minimum input current ripples due to its three-phase construction and the high frequency operation, as well as the benefit of the reduced volume and size. Also, this converter presents an important voltage elevation and a large dimming range for the input voltage, as well as a significant efficiency. The operation of the Bi-3φDAB will be explained in this paper and simulation results using MATLAB/SIMULINK will be provided to prove the converter topology's operation. Finally, detailed analysis and examination will be done.
