In this thesis, an isolated 2.5kW fullbridge DC/DC converter has been designed and analyzed regarding its efficiency and weight. By increasing the switching frequency, the magnetic components in the converter can be made smaller, in this thesis a switching frequency of 20 kHz has been compared with a switching frequency of 100 kHz. The transformer in the converter can be winded in different way...

We propose a novel dynamic hierarchical optical path network architecture that achieves efficient optical fast circuit switching. In order to complete wavelength path setup/teardown efficiently, the proposed network adaptively manages waveband paths and bundles of optical paths, which provide virtual mesh connectivity between node pairs for wavelength paths. Numerical experiments show that oper...
