Sammanfattning : In this thesis, low-loss gate-drive solutions and a proposed dv/dt-filter have been investigated with focus on train traction converters with dv/dt constraints.By using the silicon carbide (SiC) junction field-effect transistor (JFET), the switching losses can be significantly reduced compared to the commonly used insulated-gate bipolar transistor (IGBT), but complex gate-driver solutions are required for high utilization in terms of loss reduction.

Sammanfattning : Semiconductor nanowires have proven to be promising building blocks for next-generation optoelectronic devices. The nanometric dimensions of nanowires provides strain relaxation capability, thus enabling the heteroepitaxy of III-V materials on silicon, as well as providing the possibility of realizing optoelectronic devices with lattice-mismatched material combinations.
