Abstract:
The two main topics presented in this thesis are the generation and mathematical modelling of new converter structures. <br/>The fundamental idea behind the methodology used to generate the new converter structures was to break the symmetry. This involved modifying the circuit structure on the basis of the simulation results. This methodology allowed the generation of the family of asymmetrical interleaved converters, which consists of the AIDB, the AIDBB and the AIDFgroup. <br/>A new conceptual modelling approach was developed on the basis of ideas taken from previous research which is reviewed in the state of the art. This approach was called Modified Averaging Using Graphical Methods. Because of its features, this new method can be used to model the state space average of the new converter family presented here. <br/>The accuracy of the AIDB converter small signal model was verified by measuring the frequency response and by designing an LQR controller.
