Experimental Verification of a DC-DC Converter for a DC wind farm
Examensarbete för masterexamen
This thesis investigates the properties of a selection of DC-DC converters and presents the design of an experimental setup of a phase-shift controlled full-bridge DC-DC converter as well as the measurements performed with this setup. The results from the measurements confirm the simulations that were performed using the software $PSpice$. A discussion of different DC-DC converter topologies provides both a comprehensive overview of the currently available technologies as well as a theoretical background of the results of this present study. Simulation models of the phase-shift controlled full-bridge converter are analysed in detail. This study shows that the results from the simulation models widely correspond to the expected values. Further, the experimental setup is described and the results from the hardware measurements are analysed. A refined simulation model is designed on the basis of these results; this refined simulation model matches the hardware measurements to a very high degree. We conclude that the refined simulation model provides an accurate and useful tool for future research on this type of DC-DC converter. In addition, the developed hardware setup can be extended with new units and thus used for further measurements.
