| Sumario: | In this thesis, a Three-Port Active Bridge converter for high power high voltage application is designed. The design includes the Solid state high frequency transformer, and the required reactive elements the series inductors, and the DC-link capacitors. Also the choice of the switches, and the heat sink is defended, and a design of a stack for them is made, this stack will include also the driver boards of the switches and the capacitors with the bus-bars for the DC-link. The thesis also presents a simulation for each part, and a final simulation for the real model containing almost all the losses and parasitics elements. Using simulation based tools, the design for each of the parts and the full converter assembly is achieved. The simulation includes losses calculation and considers the effects of parasitic elements. The selected design is compared versus a Half-Bridge Triple Active Port topology, in order to analyze the differences in terms of efficiency, performance and reliability. Finally a simulation is presented to illustrated the behavior of the full model under the closed loop condition |
