Abstract

The dual active bridge (DAB) DC-DC converter has recently been identified as one of the most viable power electronics topologies for vehicle electrification applications, due to its galvanic isolation, bidirectional current control and high power density characteristics. However, several modulation approaches can be adopted for this converter, many of them leading to multiple degrees of freedom, making its operation complex. In particular, this project aims to carry out studies on the modulation strategy called triple-phase shift (TPS), which provides the greatest controllability for the DAB converter. In addition to studying the methodological principles of this approach, it is expected that this project will develop a computational model of a DAB converter, considering the implementation of the TPS modulation, in order to evaluate which main operational characteristics lead to greater operational flexibility within the context of an electric vehicle (EV). Furthermore, it is expected that this project will carry out an investigation that shows how intelligent algorithms can be considered when TPS modulation is used, in order to obtain greater control flexibility for the DAB converter, considering its application in EVs that can operate under the vehicle-to-grid and grid-to-vehicle modes.
