Abstract

With the rise of renewable energies, electric vehicles, and microgrids, the development of power electronic topologies that can seamlessly integrate these systems into the grid is crucial. The triple active bridge is an extension of the dual active bridge topology and is capable of energy storage or renewable energy integration into a power electronic converter and thus the power grid. Consisting of three H-Bridge converters, the triple active bridge topology is an expanding area of research to meet these growing demands. With the addition of the third bridge, the system has additional nonlinear characteristics which introduce complexity in solving for the phase shift between the bridges that facilities the power transfer between all three bridges. The Newton-Raphson Algorithm is one way to solve for the phase shift values, however the Newton-Raphson Algorithm is not completely accurate and is a feed-forward only system. Integrating feedback into the triple active bridge has sparked the development of the feedback/feed-forward controller to the dual and triple active bridge converters.

Included within this thesis is the design and validation of a feedback/feed-forward control algorithm for the dual and triple active bridge converters. The feedback/feed-forward control system is developed and validated as a proof of concept for the dual active bridge before being adapted to the DC-DC-DC triple active bridge converter. Here the feedback/feed- forward control system was vetted by the simulation and hardware validation conducted during this research. Lastly, the efforts from the AC-AC DAB and the DC-DC-DC TAB were combined to apply the feedback/feed-forward controller to the DC-AC-AC triple active bridge converter. Overall, the research present within this thesis furthered the development of various power electronic topologies by the introduction and application of a novel control method.
