DC/DC step-up converter for notebook
Škunda, Michal ; Klíma, Bohumil (oponent) ; Červinka, Dalibor (vedoucí práce)
Given bachelor’s thesis devoted to a proposal and implementation of transducer STEP-UP for supplying of notebook in car. Introduction presents dividing of switching power supplies followed by a choice and a proposal of power supply. In this work we can find the specific proposal of inductor, the proposal of electronic connexion and the proposal of PCB layout. There is a software EAGLE used for the design of PCB layout. In the last part of work there are particular courses of current and voltage that characterize power supply pictured. The work contains measured load characteristic of switching power supply loaded by notebook as well. Notebooks need to have quality power supplies that is why there was a special attention paid to the quality of supply and its electric parameters.

Switching source in electric tractions vehicle
Škunda, Michal ; Vorel, Pavel (oponent) ; Červinka, Dalibor (vedoucí práce)
The first part of this work describes the design and implementation of switch-mode power supply for control circuits for 12/2x24V 4.5A fuel cells. The introduction picks the issue of power sources in electromobiles and final design and implementation of switching power suply. The next part deals with the issues of fast-charger and generators for power transistors. It describes the structure of DC converter and control and protectin circuits of quick-charger. In the end this work describes selected driver circuits and charge tests on fast-charger as evidenced by measurements.
